<P>PROBLEM TO BE SOLVED: To efficiently exhaust drain stayed in a manifold or the like of a fuel cell stack. <P>SOLUTION: An oxidant supply manifold 400, an oxidant exhaust manifold 410, a fuel supply manifold, and a fuel exhaust manifold are installed in the fuel cell stack 50. An oxidant supplied to the oxidant supply manifold 400 is distributed to a cathode of each cell 51. The oxidant supply manifold 400 passes through the fuel cell stack 50, and has an inlet and an outlet in the fuel cell stack 50. Oxidant drain exhausting piping 200 is connected to the outlet of the oxidant supply manifold 400. Oxidant flowing through the oxidant supply manifold 400 and water 450 stayed in the oxidant supply manifold 400 flow in the oxidant drain exhaust piping 200. <P>COPYRIGHT: (C)2009,JPO&INPIT |
