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.
