Graphene supported non-precious metal based catalysts for oxygen reduction reaction(ORR)have been successfully synthesized by pyrolysis of a mixture of chromium salt,urea,and graphene oxide(GO)under n
The high cost,rare sources,easily corrosion and sluggish oxygen reduction of high precious metal based catalysts have limited the development of fuel cells.
In order to improve the work coordination of powertrain of fuel cell hybrid vehicle and solve the problems of vehicle dynamic performance and fuel economy,the main components of powertrain were select
The compressed hydrogen storage is currently widely used in fuel cell vehicles due to its simplicity in tank structure and refueling process.For safety reason,the final gas temperature in the hydrogen
