Outline
As the core product of the hydrogen energy industry, proton exchange membrane fuel cells are characterized by high energy conversion efficiency, zero emissions and no pollution. They are one of the most promising power sources in the automotive field. However, the high cost limits the largescale application and promotion of PEMFCs for vehicles. The development of lowplatinum PEMFCs for vehicles is an important technical route to improve cost competitiveness. However, the serious mass transfer and lifespan issues faced in the lowplatinum process urgently need to be solved. This paper summarizes the research progress of lowplatinum membrane electrode assembly technology and the shortcomings of existing technologies. It also looks forward to the future development trends, providing reference value for the advancement of lowplatinum membrane electrode technology for vehicle PEMFCs.
