【Abstract】 High temperature proton exchange membrane fuel cell(PEMFC)is a solution to the most important issues in the operation of traditional PEMFC,including CO poisoning and complexity in water and heat management,thus becoming the main focus in fuel cell development.Proton exchange membrane(PEM)is the core subassembly for fuel cell operation.Based on the relationship between the structure and performance of proton exchange membrane,we analyze the importance of structure design on the membrane performance,show the current research status of new emerging types of PEMs such as graft chain type PEM,composite PEM and heat-resistant PEM.For the development of PEM,inorganic/organic composite membranes(especially phosphoric acid doped(PBI),polyarylenesulfidesulfone(PASS)membranes)are regarded as the future research direction.更多还原
