The membrane electrode assembly has a resin frame member, and an inlet buffer is provided on the resin frame member adjacent to the fuel gas supply passage. The inlet buffer includes a first buffer area adjacent to the fuel gas supply passage and a second buffer area adjacent to a fuel gas flow field. The opening dimension of the first buffer area in a stacking direction is larger than the opening dimension of the second buffer area in the stacking direction.
