MANUFACTURING METHOD OF FUEL CELL

摘要

PROBLEM TO BE SOLVED: To make it possible to securely join a step electrolyte membrane electrode structure and a resin frame member with a simple step.SOLUTION: The manufacturing method of a fuel cell 10 includes steps of: individually producing a step MEA 12a and a resin frame member 24; molding an adhesive sheet 26 having a frame shape by following a shape of an adhesive joint portion between the step MEA 12a and the resin frame member 24; and bonding an inner periphery projection 24a of the resin frame member 24 and an outer peripheral edge of the step MEA 12a with the adhesive sheet 26.
