Abstract
A resin film equipped MEA of a power generation cell includes a membrane electrode assembly and a resin film. An inner peripheral end of a first frame shaped sheet of the resin film is positioned outside an outer peripheral end of a cathode, and faces the outer peripheral end of the cathode so as to be separated by a gap. An inner peripheral portion of a second frame shaped sheet is held between the anode and the cathode. A first metal separator facing the first frame shaped sheet is provided with protruding support structure configured to support an inner peripheral portion of the first frame shaped sheet and an outer peripheral portion of the cathode.

A power generation cell comprising a resin film equipped MEA and a pair of separators provided on both sides of the resin film equipped MEA,
- the resin film equipped MEA comprising:
- a membrane electrode assembly including an electrolyte membrane and a first electrode and a second electrode provided respectively on both sides of the electrolyte membrane;
- and
- a frame shaped resin film provided on an outer peripheral portion of the membrane electrode assembly over an entire periphery,
- wherein the resin film is formed by stacking a first frame shaped sheet and a second frame shaped sheet together;
- an inner peripheral end of the first frame shaped sheet is positioned outside an outer peripheral end of the first electrode, and faces the outer peripheral end of the first electrode so as to be separated by a gap;
- an inner peripheral portion of the second frame shaped sheet is held between the first electrode and the second electrode;
- and
- a separator facing the first frame shaped sheet, of the pair of separators, is provided with protruding support structure configured to support an inner peripheral portion of the first frame shaped sheet and an outer peripheral portion of the first electrode.
