Title:
METHOD FOR MANUFACTURING MEMBRANE-ELECTRODE ASSEMBLY
Document Type and Number:
Japanese Patent JP2010056004
Kind Code:
A
Abstract:

To provide a method for manufacturing a membrane-electrode assembly capable of sufficiently restraining wrinkles and cracks of a polymer electrolyte membrane and a catalyst layer caused by dimensional changes of the polymer electrolyte membrane formed by applying a catalyst ink to the polymer electrolyte membrane.

In the manufacturing method for the membrane-electrode assembly having a structure where a catalyst layer is laminated on the surface of the polymer electrolyte membrane, the polymer electrolyte membrane includes a catalyst layer formation process of forming the catalyst layer on the surface of the polymer electrolyte membrane by preparing a membrane-base material assembly joined with peeling-off adhesion strength of 10 N/m or more on the surface of a film base material having a low swelling property in a plane direction in comparison with the polymer electrolyte membrane and by applying the catalyst ink including at least an electrode catalyst and a solvent on the surface of the polymer electrolyte membrane of the membrane-base material assembly; and a base material peeling-off process of peeling off the film base material from the surface of the polymer electrolyte membrane.
