POLYMER ELECTROLYTE MEMBRANES FOR USE IN FUEL CELLS

摘要

This invention relates to a polymer electrolyte membrane comprising a proton conducting hydrocarbon-based polymer membrane, the polymer having a backbone and having acidic groups on side chains attached to the backbone. The invention also relates to a polymer electrolyte membrane comprising a proton conducting hydrocarbon-based polymer membrane having a phase separated morphological microstructure. The invention also relates to a polymer electrolyte membrane comprising a proton conducting membrane, the membrane comprising a basic material in combination with an acidic material selected from acidic hydrocarbon-based polymers, acidic hydrocarbon-based oligomers, and blends thereof.
