ELECTRODE FOR FUEL CELL AND MANUFACTURING METHOD THEREFOR, SOLID POLYMER FUEL CELL, AND CATALYST INK

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of suppressing generation of cracking even after an electrode is prepared with catalyst ink containing electrolyte resin having high oxygen permeability.

SOLUTION: The electrode for fuel cell is prepared with catalyst ink containing: a catalyst carrier that is a conductive carrier with supported catalyst; first electrolyte resin having oxygen permeability of less than 2.2×10-14mol/(m s Pa) under the surroundings of a temperature of 80°C and a relative humidity of 50%; and second electrolyte resin having oxygen permeability of 2.2×10-14mol/(m s Pa) or more under the surroundings of a temperature of 80°C and a relative humidity of 50%.
