ELECTROLYTE MEMBRANE FOR POLYMER ELECTROLYTE FUEL CELL AND MEMBRANE ELECTRODE ASSEMBLY FOR POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a polymer electrolyte fuel cell capable of generating electric power at high energy efficiency having high power generation performance independent of a dew point of supply gas, and conducting stable power generation for a long time.

SOLUTION: A polymer electrolyte membrane 1 manufactured by including cobalt ions in a cation exchange membrane comprising a polymer compound having a sulfonic group is used as an electrolyte membrane for the polymer electrolyte fuel cell. A cobalt ion-containing membrane/electrode assembly 7 is used in at least one of an anode catalyst layer and a cathode catalyst layer 3 containing an ion exchange membrane having catalyst powder and a sulfonic group.
