Abstract
A membrane electrode assembly includes an electrolyte membran and frame-shaped first and second gaskets disposed on both surfaces of the electrolyte membrane. The first and second gaskets have overlapping portions which are positioned at a peripheral edge of the electrolyte membrane and face to the electrolyte membrane, and bonding portions which are positioned outside of the peripheral edge and bonded to each other. The overlapping portions and the bonding portions have through holes which extend in a thickness direction of the electrolyte membrane. An aperture ratio of the through holes of the overlapping portions is greater than an aperture ratio of the through holes of the bonding.
