In the membrane electrode assembly (12), a surface area of a gas diffusion layer (42a) is larger than a surface area of a gas diffusion layer (42b). A seal member (60) is provided at a position corresponding to an outer marginal region (45) of the gas diffusion layer (42a). The seal member (60) includes a main seal (62) inserted between a solid polymer electrolyte membrane (36) and the first metal separator (14), and an a flow field wall (64) inserted between the gas diffusion layer (42b) and the first metal separator (14) for defining a part of an oxygen-containing gas flow field (46).",
