Document Type and Number:
Japanese Patent JP5140898
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a membrane-electrode joined body having performance higher than a conventional one, and suppressing degradation of strength of proton exchange membrane and decrease of ion exchange ability. SOLUTION: In a joining process of membrane-electrode joined body comprising at least a proton exchange membrane, an electrode catalyst layer and an electrode base material, the proton exchange membrane and/or an electrode catalyst layer previously containing a solvent are used, and the solvent is evaporated from the proton exchange membrane and/or the electrode catalyst layer by pressurizing and heating them.
