(228c) Electrochemical Energy Storage and Conversion System Integration and Application for New Energy Vehicle and CO2 Utilization

Energy storage systems are very important for the new energy vehicle. Electric vehicles (EVs) including the fuel cell electric vehicle (FCEV) are one of the most important new energy vehicles. The obstacle to the commercialization for EVs is hydrogen storage and electricity storage with low cost, high density and safety. According to the expertise from the demonstration of the FCEV and PHEV in the world, all-electricity drive motor system which integrated with advanced battery or supercapacitor with fuel cell stack will become the promising power system for the solution of green and sustainable vehicle. Fuel cells will play an important role in the new energy vehicle. The National Basic Research Program (973 Program) is China's on-going national keystone basic research program, which was approved by the Chinese government in June 1997 and is organized and implemented by the Ministry of Science and Technology (MOST) of China. Based on the demonstration activities of the FCEV and other new energy vehicles during 2008 Beijing Olympic and 2010 Shanghai EXPO, we found that it is important to study the lower cost materials and the process engineering issue for fuel cell electric vehicle. At the meantime, one 973 project titled of ?Basic study to energy storage system (Hydrogen & electricity storage) with low cost and high power density for electric vehicle? was started since 2007. Many research groups those come from different universities and institute were involved in this project. In this project, the researches focused on several topics, such as molecular design and synthesis of hydrogen storage materials with high capacities, fundamental studies of lower cost electrochemical supercapacitors and advanced secondary batteries and basic study of solid-state electrolytes and related electrode materials for solid oxide fuel cell. The applied fundamental research on electrode materials and function in CO2 emission reduction and utilization of solid oxide cell were also involved. This talk will present some of the research progress of these projects in detail.
