Abstract

A fuel cell including: a fuel cell stack; a pair of end plates holding the fuel cell stack by tightening from both ends; and a plurality of gas manifolds fixed to the fuel cell stack and end plates with the sealing members therebetween to supply fuel and oxidant to each of fuel gas flow paths and oxidant gas flow paths of the fuel cell stack, the fuel cell includes: a gas manifold fixing band including: hold plates installed in contact with a back of the gas manifold; a hold plate connecting part connecting the hold plates installed on the backs of adjacent gas manifolds; and a band-tightening part connecting and tightening both ends of a series of hold plates and the hold plate connecting part.
