New Microbial Fuel Cell
To power the new car coming out microbial fuel cell
The face of energy-saving technology bottleneck automobile industry to find new alternative sources of energy has become an important area of automotive energy-saving environmental protection issues. Recently, in the car, "Energy Conservation and Green Manufacturing" summit forum, from Xiamen University, School of Chemistry and Chemical Engineering Associate Professor Xu Fangcheng introduced a new type of microbial fuel cell, energy-saving environmental protection for the vehicle to provide a solution.
As the name suggests, this microbial fuel cell is a microorganism as a "fuel", through a series of chemical reactions, into energy to power cars. This is a microbial fuel cell sugars, organic waste, organic solid waste as raw material by chemical reaction of the device specifically to generate electricity or hydrogen, into the super-capacitor or hydrogen fuel cells, eventually forming power.
According to reports, this fuel cell from the battery and storage capacity of the battery component, parking can be achieved when the power generation and storage, security and environmental protection. The main sources of fuel such as straw and other crops, and are easy to convert waste water. Xufang Cheng said: "This technology can reach 1,000 grams of glucose in the final of the energy equivalent to 4 liters of gasoline."

Check quality and to promote development, China's first solar cell industry standard introduced
Recently, China's first solar industry standard glass used in building by the National Organization of Standardization Technical Committee held a "solar glass (commonly known as solar glass) industry standard" approved at the meeting.
The standard proposed solar iron content of glass not more than 0.015%, visible light transmittance greater than or equal to 91.5% (or about 3mm thickness), direct solar transmittance greater than or equal to 91.0% (equivalent to the standard thickness of 3mm).
The standard certified by the China Building Material Test Center drafted. Said standard solar glass is used to cover film crystalline silicon solar cells with high projection than glass. It is learned that the solar cell glass, there is no corresponding international standards can reference the relevant domestic and foreign enterprises generally formulate its own corporate standards were merely used for production control, or incoming inspection. Because there is no unified standard, solar glass industry development and standardization severely constrained.
Experts said that the development of standards, will be related to quality control and inspection company an important reference for the glass industry in promoting the development of solar energy will play an active role. In addition, the industry standard will seek to raise to a higher platform, and strive to become the national standard.

Chemical fuel cell research have much to accomplish
Chemical fuel cell research have much to accomplish
Two year period, the first CPPCC National Committee members, the National "863" energy saving and new energy automotive fuel cell engine project leader, our hydrogen fuel cell engine experts, general manager of Shanghai divine power Technology Co., Ltd. Dr. Hu Liqing, submitted a "new energy and new energy vehicle development policies issued, "the proposal. After returning to Shanghai, Hu Li Qing is linked with the reporter, on the subject of the industrialization of fuel cell technology. Appeal to the domestic chemical companies and research institutes involved in hydrogen fuel cell capture bottleneck, truly clean car technology for China's leap-forward development.
Fuel cell technology has yet to play a dominant
Introduced in the Qing Hu, "15" during the national "863 electric cars in the major projects" funding, the Shanghai R & D success of divine power technology pioneered air pressure, low pressure hydrogen to run cars and city buses with fuel cell engine used in The main technical indicators have reached international advanced level.
In 2006, the divine power technology began to take the national "Eleventh Five-Year ... '863" energy saving and new energy vehicles to launch major projects ridiculed fuel cell R & D production, but due to market and cost factors, divine power the fuel cell engine technology has been small mass production.
Industrialization of fuel cell engines to meet the opportunities
During the two sessions, more aware of the Qing Hu in the industrialization of fuel cell engines urgency. In his view, energy security and environmental protection strategies starting to realize innovation of new energy vehicles, the opportunity has come leaps and bounds.
All countries in the developing world production of new energy vehicles. For a long period of time, a variety of new energy technology cars are opportunities for development. The hydrogen fuel cell vehicles is the world recognized the ultimate zero-emission fuel-efficient vehicles technology solutions in the automotive sector, the development of energy saving direction. Hydrogen fuel is a renewable energy from coal gasification, coke, alkali and other chemical industries were purified by-product of hydrogen recovery, with good economy. China should accelerate the development of hydrogen fuel cell vehicle industry, the pace, and walk in the world.
Key breakthroughs in three key materials
Li Qing Hu told reporters that the industrialization of fuel cell technology involves two aspects of fuel cell technology itself, the second form fuel cell materials and components. Fuel cell from the global and China's state industrial development point of view, superior performance, the raw materials industry is the key to the industrialization of fuel cells, but also improve fuel cell performance and lower cost determining factor.
Julio clear analysis of current domestic hydrogen fuel cell engines are dominated by the cost of fuel cell heap, there are three needs to import raw materials, namely, proton exchange membrane, carbon fiber paper and carbon containing platinum catalyst, so the cost of our hydrogen fuel cells more high. However, mass production in future, especially if the localized three types of raw materials, large-scale production, manufacturing costs will be greatly reduced.
The first "three-electrode" in the proton exchange membrane industrialization. The electrode material plays a barrier in the hydrogen fuel mixed with oxygen, the role of oxidant, but it is also the proton hydration free passage of the conductor and insulator electronics can not. In the fuel cell operating conditions, the membrane must have good mechanical strength and electrochemical stability, have a certain moisture content, and a more stable physical size. Currently used proton exchange membrane of DuPont products.
Second is the "triple electrode" in the industrialization of the gas diffusion layer materials. The material in the electrode catalyst layer plays a supporting, stabilizing role of electrode structure, while also providing feedback to the fuel electrode gas Tongdao, electronic channels and drainage channels, the different diffusion layer materials for the electrode structure, manufacturing process and properties also different. Several commonly used. A carbon fiber paper, carbon cloth and nonwoven cloth.
Third, the carbon electrodes containing platinum catalyst industrialization. The catalyst to help accelerate the anode electrode in the fuel into hydrogen and oxygen to help speed up the reduction of two types of cathode catalyst oxidizer. Currently, many units of domestic R & D of carbon in the platinum catalyst containing platinum and the Philippines. And progress in industrialization, but away from the advanced level there are still some gaps.
The three key raw materials, fuel cells are dependent localization of the domestic chemical industry, research institutes or enterprises in innovative research and development. Dr. Hu Liqing expect the chemical industry for the industrialization of fuel cell technology to contribute.
