Abstract
A checking method of a resin-framed membrane electrode assembly includes checking whether there is breakage in one of short sides of a first rectangular peripheral shape of a clearance provided in the resin-framed membrane electrode assembly without checking whether there is breakage in any other part of the clearance, the resin-framed membrane assembly including a solid polymer electrolyte membrane, a gas diffusion layer provided on the solid polymer electrolyte membrane, and a resin frame member that has a second rectangular peripheral shape and surrounds the solid polymer electrolyte membrane and the gas diffusion layer to provide the clearance between the resin frame member and the gas diffusion layer, the solid polymer electrolyte membrane being made from a solid polymer electrolyte membrane roll in which a solid polymer electrolyte membrane sheet is wound in a winding direction, long sides of the rectangular peripheral shape extending in the winding direction.
