COATING LIQUID FOR ELECTROLYTE FOR SOLID POLYMER ELECTROLYTE FUEL CELL AND METHOD FOR PRODUCING ELECTRODE FOR SOLID POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a stabilized ion exchanger polymer solution for a solid polymeric electrolyte fuel cell for a long period, to obtain a highly durable electrode. SOLUTION: An ion exchanger polymer consisting of a fluorine contained polymer containing functional groups capable of cross-linkage with covalent bond and sulfonic acid groups and being a dry resin having an ion exchange capacity of 1.0-4.0 milli-equivalent/g is dissolved in a solvent.
