MANUFACTURING METHOD FOR MEMBRANE ELECTRODE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a membrane electrode assembly preventing bend of an electrode of a membrane electrode assembly for a fuel cell produced by using the electrophoresis method and preventing deterioration of a solid polymer electrolyte film.

SOLUTION: The manufacturing method for a membrane electrode assembly of this invention which is a method for manufacturing the membrane electrode assembly of the solid polymer electrolyte fuel cell by the electrophoresis method comprises a process forming gaskets on both sides of the solid polymer electrolyte film, a process arranging electrophoresis cells on both sides of the solid polymer electrolyte film sandwiching the gasket, a process forming the electrodes in opening parts of the gaskets using the electrophoresis method for manufacturing the membrane electrode assembly, a process taking out the membrane electrode assembly with the gaskets from the electrophoresis cell after termination of electrophoresis and a process which incorporates the membrane electrode assembly with the gasket in a separator.
