摘要:
A highly proton conductive polymer electrolyte composite membrane for a fuel cell is provided. The composite membrane includes crosslinked polyvinylsulfonic acid. The composite membrane is produced by impregnating a mixed solution of vinylsulfonic acid as a monomer, a hydroxyl group-containing bisacrylamide as a crosslinking agent and a photoinitiator or thermal initiator into a microporous polymer support, polymerizing the monomer, and simultaneously thermal-crosslinking or photo-crosslinking the polymer to form a chemically crosslinked polymer electrolyte membrane which is also physically crosslinked with the porous support. Further provided is a method for producing the composite membrane in a simple manner at low cost as well as a fuel cell using the composite membrane.
