FUEL CELL

Abstract

The fuel cell includes a resin frame body having an opening portion, a membrane electrode assembly disposed in the opening, and a first separator and a second separator opposed to each other via the frame body and the membrane electrode assembly. A first manifold hole is formed in the frame body, the first separator, and the second separator. A plurality of first gas passages extending from the first manifold hole to the membrane electrode assembly are opened in a first region that is a part of the inner peripheral face of the first manifold hole. The first gas passages are formed between the frame body and the first separator. In the first region, in the cross section passing through the central axis of the first manifold hole, the inner wall face of the first separator protrudes toward the central axis side than the inner wall face of the frame body.
