Title:
燃料電池発電システムおよびその運転方法
Document Type and Number:
Japanese Patent JP5303419
Kind Code:
B2
Abstract:
A fuel cell power system and an operating method thereof are proposed in which, the power generation performance of the fuel cell is effectively recovered in a short period of time without additionally requiring any reducing agent or an inactive gas and while minimizing the degradation of the catalyst in use. The fuel cell power system includes a fuel cell stack in which a plurality of cells each having a membrane electrode assembly and a separator are stacked and a secondary battery which can be charged by power generated by the fuel cell stack. The fuel cell power system can supply power from either the fuel cell stack or the secondary battery to an external device. The fuel cell power system is provided with a power generation cell connection/disconnection mechanism for individually connecting and disconnecting a conductor for electrical conduction between the anode and cathode of each cell included in the fuel cell stack which controlled by a control unit.
