MEMBRANE FOR FUEL CELL AND MANUFACTURING METHOD OF ELECTRODE JOINT BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for providing a membrane and an electrode joint body each having a smooth joint surface without generating a crease on an electrolyte membrane, in a method for forming a catalyst layer on an electrolyte membrane by using catalyst ink.

SOLUTION: This manufacturing method of a membrane for a fuel cell and an electrode joint body for applying catalyst ink containing an electrolyte and catalyst to a surface of an electrolyte membrane is characterized by that the catalyst ink further contains an acid.
