Abstract
A unit cell of a fuel cell includes a membrane electrode assembly and a cathode side separator and an anode side separator sandwiching the membrane electrode assembly. An oxygen-containing gas supply passage connected to an oxygen-containing gas flow field is formed in the cathode side separator. The oxygen-containing gas supply passage has a rectangular shape extending in a flow field width direction of the oxygen-containing gas flow field. The width of the opening of the oxygen-containing gas supply passage on the short side is increased from the end side to the central side in the flow field width direction.
