SOLID POLYMER ELECTROLYTE MEMBRANE, FUEL CELL USING THIS, AND METHOD OF MANUFACTURING THE SOLID POLYMER ELECTROLYTE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To reduce crossover while retaining ion conductivity of a polymer electrolyte membrane with a simple method.

SOLUTION: The fuel cell is manufactured (S104) by using the polymer electrolyte membrane manufactured by: a step (S100) for wetting a solid electrolyte film with water; and a step (S102) for heat-pressing the polymer electrolyte membrane with the polymer electrolyte membrane in a wetted state in water.
