SOLID POLYMER ELECTROLYTE AND PROCESS FOR MAKING SAME

摘要

A method for preparing a polymer electrolyte membrane comprising:
(a) preparing an ink solution comprising a precious metal catalyst on a supporting particle and an ion exchange material;
(b) providing a polymeric support having a microstructure of micropores;
(c) applying either the ink solution or a solution comprising an ion exchange resin to the polymeric support;
(d) optionally, repeating step (c);
wherein at least one application in step (c) or (d) uses the ink solution.
