The separator of which the region facing the MEA is a flat includes the first electrode facing plate and the second electrode facing plate. The separator includes the reaction gas supply manifold to which the reaction gas is supplied. The first electrode facing plate includes a plurality of reaction gas supply holes formed at the end of the cell-reaction region. The intermediate plate includes a plurality of reaction gas supply path slits that forms the reaction gas supply paths, wherein each of the reaction gas supply paths has one end connected to the reaction gas supply manifold and other end connected to at least one of the plurality of reaction gas supply holes.

Fuel cell separator

In a fuel cell including a gasket, which includes a lip portion, as a sealing member, the fuel cell includes a fuel cell constituent element () disposed adjacent to the lip portion () of the gasket (), and a non-adhesive layer () disposed between the gasket () and the fuel cell constituent element ().

Fuel cell and gasket for fuel cell

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.
