POLYMER ELECTROLYTE FUEL CELLS WITH HIGH FREEZE/THAW DURABILITY

摘要

PURPOSE: A polymer electrolyte fuel cell is provided to suppress separation between electrolyte and electrode or electrode and gas diffusion layer and to ensure high durability in a freezing condition. CONSTITUTION: A polymer electrolyte fuel cells having durability comprises: a perfluoro sulfonic acid elelctrolyte membrane and a gas diffusion layer with both sides of a membrane-electrode assembly. The polymer electrolyte membrane is perfluorinated sulfonic acid nafion membrane, flemion membrane, asiplex membrane, or Dow XUS membrane.
