A frame is provided in an outer end of the membrane electrode assembly. A seal member is formed on the frame. The seal member includes a first seal as a fuel gas seal, a second seal as a coolant seal, and a third seal as an oxygen-containing gas seal. The first seal, the second seal, and the third seal are offset from each other in the stacking direction.
