Abstract
A separator of a fuel cell stack, which has flat surfaces that face MEAs, includes a cathode-side plate, an anode-side plate and an intermediate plate. The intermediate plate has a plurality of oxidant gas supply channel openings that communicate with an oxidant gas supply manifold and oxidant gas supply holes of the cathode-side plate, and a plurality of oxidant gas exhaust channel openings that communicate with an oxidant gas exhaust manifold and oxidant gas exhaust holes of the anode-side plate. The width and spacing of the oxidant gas exhaust channel openings are set to be larger than those of the oxidant gas supply channel openings.
