    Battery tips No Comments

    Ulster University, Institute of Nano Technology Peking University and the Oxford scientists and university collaborators in Nov. 20, 2010 announced the development of the reduction of graphite oxide / platinum catalyst as the carrier power (Pt / RGO) (see Figure 1X-ray spectroscopy ), is expected to manufacture the fuel cells more efficient and more resistant to carbon monoxide (CO) poisoning.

    Catalyst for this new power to improve the design of fuel cells is expected to be durable and to avoid using expensive dual-metal or tri-metal system, which can fuel cell vehicles to contribute to the practical.
        The results have been published in the American Chemical Society, “Physical Chemistry C book (Journal of Physical chemistry C)” on.

    The system has been tested and has the potential of methanol electro-oxidation can be used as anode material. And business as a carrier of carbon compared to Pt electrocatalysts, Pt / RGO show excellent performance of resistance to CO poisoning, a high electrochemical activity for methanol oxidation of the surface and a high catalytic activity, verify that the above performance 110% respectively, 1345 and 60%.

    Chemical energy directly into electricity through the electrochemical fuel cell system is decomposed into hydrogen fuel, or consider the use of methanol as a drive vehicles and portable facilities for promising new method for fuel cells. Commercial application of fuel cells is an important obstacle to the activity of CO poisoned platinum catalyst active center, which will lead to failure and to prevent fuel oxidation. CO poisoning problem in direct methanol fuel cells (DMFCs) is especially serious, because as the oxidation of methanol as an intermediate product, CO key number always exists.

    So far, an important way to reduce the poisoning is high with other metals such as platinum Ru, Pd or Au alloy. The researchers found a little expensive solution pro. CO creating a more tolerant catalyst system, the platinum nano-crystalline graphite oxide deposited on carrier material, and make it a little to restore order to increase its conductivity.

    The researchers used a simple, expandable and fast microwave channels can be restored with graphite oxide (RGO) and the formation of platinum nanoparticles while the benefits. To test the Pt / RGO activity, the research team observed the oxidation of methanol. The results show that the new material shows excellent resistance to CO poisoning sexuality, and commercially available carbon supports Pt (Pt / C) electrocatalyst, compared with a better long-term stability and high electrocatalytic activity.

    six measures to prevent battery from freezing in Winter

    Battery tips No Comments

    Combine hands on some machines, four-wheel tractors and other agricultural vehicles after the closure of about improper maintenance batteries, battery resulting in cold and difficult to repair or scrapped. Therefore, enter the winter, the battery should take the following conservation measures:

    Greenhouse elevated storage battery when not in the house on the preservation of more than 0 ℃, should not be placed directly on the ground. External storage batteries before the first wash, add a little electrolyte, fully charged and tighten the drain plug. Once every other month after the additional charge, once every two weeks check the electrolyte fluid level, low added immediately. This can protect the battery safety through the winter.

    Improve the ratio of liquid electrolyte composed of water and sulfuric acid, the higher the content of sulfuric acid in the electrolyte, the higher the proportion of the electrolyte, the lower the temperature of electrolyte freezing. To this end, throughout the winter minimum temperature according to the local select the appropriate proportion of the electrolyte to prevent the electrolyte freezing.

    Enough power to keep the state in the winter, when the battery discharge 50%, there is the risk of ice electrolyte. To this end, the winter discharge of the battery level does not allow more than 50%. In winter, we should always check the battery storage of electricity, lack of timely and should be added.

    Raise the temperature of the electrolyte temperature electrolysis capacity of the battery a great impact on the environment temperature decreasing by 1 ℃, capacity reduction of about 1% - 2%. Therefore, to improve the temperature of the electrolyte, motorcycle parking should be indoors, or move the battery interior above 0 ℃.

    Liquid water mixed with electrolyte batteries by adding distilled water should be mixed. If the time to mix well, floating in the electrolyte will freeze the top of the distilled water. Add distilled water this winter to the battery, immediately to its charge, or side of distilled water while charging, electrolyte and distilled water can quickly mixed, not frozen.

    Start checking your system periodically should be checked regularly maintained. Adjustable voltage regulator, the charging voltage increased to 0.60V. Each time you start not allowed more than 3 - 5 seconds, a start not, and should be stopped 1 minute after the start. Start the long hours will damage the starter motor and battery.

    “Artificial leaves” is a new generation of solar cells

    Battery tips No Comments

    North Carolina State University research team has demonstrated a new solar installations - “artificial leaves.” The equipment is based hydrogel, the same can be like a solar cell to produce electricity and is expected to cost less than current silicon-based solar cells, environmental protection and better.

    “Artificial leaves” filled with photosensitive molecules from the water-based gel composition, with two electrodes coated with carbon material, the researchers had used in the experiments as the photosensitive chlorophyll molecules.

    North Carolina State University professor (Orlin Velev) said that as plant molecular synthesis of sugar by stimulating the same photosensitive molecules excited by the sun’s rays to produce electricity. The research paper published in the “Materials Chemistry book” online edition, Weili Fu as the main author.

    The team hopes to be able to figure out how to mimic the use of solar energy in the natural material. Although the “artificial leaves” to use artificial photosensitive molecules, but because the device is a hydrogel matrix, the derivative of chlorophyll and other natural materials can be easily integrated in..

    Weili Fu said the researchers fine-tune the water-based optoelectronic devices, bringing them closer to the true leaves. He said: “The next step is to imitate the plants found in the self-regeneration mechanism. Another challenge is to change the water-based gel and photosensitive molecules, to improve the efficiency of solar cells.”

    Weili Fu even imagine a future full of the roof covered with “artificial leaves” scenario of solar cells, he said: “We can not expect too much at this stage, the device’s efficiency is still relatively low, before becoming a practical technology, There is still a long way to go. However, we believe that bio-inspired ’soft’ power generation unit may become the future of alternative solid-state technology. “

    solar components industry shifting to Asia in order to reduce the manufacturing cost

    Battery tips No Comments

    Solar modules currently the biggest challenge facing the industry is how to reduce the solar module manufacturing costs to improve the capacity. In view of this market demand, IMS market research firm recently announced its results, as of the fourth quarter of 2010, the Asian market, the production of components have been accounted for more than 70% of global production. Meanwhile, IMS also pointed out that this production shift to Asia, the trend does not stop there, is expected to end in 2011, global production of photovoltaic products, more than 75% will be transferred to Asia.

    IMS said in 2010, the development of the component industry is a very good year, a spate of production increased demand for shipments of restricted price increases and so on. At the same time, when the whole industry is preparing to enter the time in 2011, IMS said, when the PV suppliers within the industry have turned their attention to how to reduce the production cost of components listed on the German market is gradually saturated.

    Therefore, each supplier’s production plant will be transferred gradually to the lower component production costs can be achieved in Asia, where REC is a good example of the company. IMS has stressed, REC’s Singapore-based fully automatic wafer, cell and module production line in late 2011 to € 0.97 per watt production cost components. In addition, IMS has also cited Evergreen Solar (EvergreenSolar, NASDAQESLR) example of the company, the company plans to end of 2012 at its factory in China 90 cents per watt manufacturing costs of components, relative to their 2010 In the third quarter of its U.S. plants produced by the same component cost down to $ 1.88 per watt for the move, with major changes.

    “To achieve the sustainability of the PV industry fat and reduce its dependence on Government subsidies to reduce the cost of photovoltaic products, price is a very important aspect. Seen in this light, the same as other large-volume ic37, the manufacturing base transferred to the Asian region, it is imperative for the photovoltaic industry. “PV field analyst Sam Wilkinson (SamWilkinsON) said,” There is a large-scale leading Chinese manufacturer of crystalline silicon PV modules within the industry price trends. and other Western markets by vendors are also production lines to Asia to actively join the ranks of the price. “

    two major progress in Solid oxide fuel cell research

    Battery tips No Comments

    Harvard University scientists recently reported in solid oxide fuel cells (SOFCs) the progress achieved in the field are two: one is the battery is no longer used platinum material; the other is the battery’s operating temperature down to 300 degrees Celsius to 500 degrees Celsius. The researchers said that based on the operation of SOFCs at lower temperatures, more abundant and more expensive fuel source material progress, SOFCs may soon become a mainstream technology, the future will give laptop computer or mobile phone power supply.

    Harvard University Institute of Engineering and Applied Science (SEAS) of the Larsen SOFCs experts and innovators, and his research team published in this month’s “Power Magazine” presented their latest results.

    SOFCs are third-generation fuel cell, this all solid-state chemical power generation device can be directly in high temperature conditions will be stored in the fuel and oxidizer in the chemical energy efficient and environmentally friendly manner into electricity. However, reliability, temperature, and the cost has been the use of SOFCs to the laptop computer, cell phone charging or drive the next generation of cars and trucks, are experiencing a “stumbling block.”

    In SOFCs, the oxygen ions from the cathode through the electrolyte Chaoyang very backdrop to the anodic current and back to the cathode. The principle seems simple, but so far, SOFCs have been more suitable for laboratory and not the office or car.

    Raman Larsen team in the first paper to introduce a stable operation, functional full-ceramic thin-film battery, the most important is that this cell does not require platinum material. Platinum is commonly used in micro-SOFCs electrode material, but platinum is very expensive and unstable. Raman Larsen said that if the use of porous metal electrodes, essence, they may not remain stable for a long time, will gather in lumps and in the manufacture of fuel cell open circuit. Thus, in its development of new film SOFCs, the researchers used a special ceramic membrane close parcel layer (the thickness of each layer is only a few nanometers), only do not need platinum or a porous metal electrode, the electrolyte will also use reduced to the previous or even thousandths of one percent, so that the new battery lower cost and higher reliability.

    Traditional SOFCs operating temperature is generally 800 degrees Celsius to 1000 degrees Celsius, with a smart phone they can not charge. In recent years, materials scientists have been trying to reduce the operating temperature to 300 degrees Celsius to 500 degrees Celsius. Moreover, when the fuel cell operating at lower temperatures, the material is no longer so critical, it allows a less expensive ceramic and metal combination.

    Raman Larsen said that in this field, the temperature is the “Holy Grail.” If we can allow efficient SOFCs at 300 degrees Celsius to 500 degrees Celsius to run, people can transport or use them on portable electronic products, and can use different fuel sources.

    Research team developed a new SOFCs using abundant and cheap natural gas methane. So far, SOFCs is the main fuel used in hydrogen, Raman said Larsen, manufacture pure hydrogen is very expensive, which limits the scope of application of SOFCs. Replace the hydrogen with methane as the main fuel source SOFCs, in temperature, reliability and price of progress made to strengthen each other.

    Raman Larsen added, they will conduct further studies to explore a new catalyst for methane SOFCs, and ultimately find a cheap abundant, help to further reduce the operating temperature of the material.

    Assistant Professor of Electronic Engineering at Harvard University research team led by Robert Wood, is currently developing a small flying robot RoboBees project aims to use new technology developed a low-power, high storage capacity, highly intelligent, sustainable flight bionic flying robot. Raman Larsen and Wood hope that the new micro-SOFCs can provide power for the robot, let off the ground.
