ABSTRACT:
To provide a fuel cell and an oxidant distributing plate for the fuel cell. A water created in the fuel cell is used to humidify an oxidant gas and/or a fuel flowing in an opposite passage opposite to a MEA. The fuel cell includes a MEA1, an oxidant distributing plate3disposed facing to an oxidant pole for supplying an oxidant gas thereto, and a fuel distributing plate4disposed facing to an fuel pole for supplying the fuel thereto. At least one of the oxidant distributing plate3and the fuel distributing plate4is provided with an opposite passage31, 41formed on an opposite surface opposite to the MEA, and a reaction passage32, 42formed on a facing surface facing to the MEA, and communicated with the opposite passage31, 41.
