Abstract
A membrane electrode assembly for a fuel cell that secures a flow path of a separator while preventing generation of a pin-hole. The membrane electrode assembly includes an electrolyte membrane for a fuel cell, a microporous layer that is disposed at both surfaces of the electrolyte membrane, a backing layer that is disposed on the microporous layer, and a circumferential edge protective layer that is disposed at an circumferential edge of the electrolyte membrane. An end portion of the microporous layer is positioned further inside of the membrane electrode assembly than an end portion of the backing layer. The circumferential edge protective layer is inserted between the backing layer and the electrolyte membrane.
