PURPOSE:To provide uniform temp. distribution and enhance the efficiency by setting the coefficient of heat transfer from an oxidating agent gas to a flow path therefore so that heat transfer will scarcely be generated between oxidating gases each other of adjoining unitary cells. CONSTITUTION:In the strata structure 11 of a fuel cell 11, unitary cell laminate blocks 15a-15e are furnished between five cooling plates 14a-14e. The flow path 18 in these cooling plates face the flow of oxidating agent and is suppressed low in a degree so as not to generate heat transfer between the oxidating agent and cooling agent. In the cooling plates 14a-14e the cooling agent in the stream indicated by arrow c flows in the direction facing the oxidating agent in the stream as Q in blocks 15a-15e. The temp. distribution on the strata structure 11 in the plane direction can be suppressed uniform by suppressing low the coefficient of heat transfer of the flow path 18 to the cooling agent or oxidating agent in such a degree as not to generate heat transfer between the oxidating and cooling agents. |
