Abstract
To provide a polymer electrolyte fuel cell in which a reaction gas can be utilized efficiently for an electrode reaction even when a gap is formed between an anode-side sealing member and the end face of an anode and between a cathode-side sealing member and the end face of a cathode, and sufficient power generation performance can be ensured with a simple constitution. At least one of the anode-side sealing member and the cathode-side sealing member of the fuel cell includes an annular body, and at least one deformable protruding portion provided on the inner surface of the annular body.
