Fuel cell stack |
摘要 |
A fuel cell stack is equipped with a stacked body constituted by stacking a plurality of power generating elements, which contain an electrolytic membrane and electrocatalytic layers arranged at both surfaces of the electrolytic membrane, via a separator for providing a flow path for supplying reaction gas to the electrocatalytic layer, and collector plates arranged at both ends of the stacked body, for collecting electricity generated by the stacked body and outputting it to the outside, wherein on the separator and the collector plate are formed at least one of an anode exhaust gas exhaust hole for exhausting anode exhaust gas, a cathode exhaust gas exhaust hole for exhausting cathode exhaust gas, and a medium supply hole for supplying into the stacked body a medium for maintaining the temperature of the stacked body at an approximately fixed level, and at the anode side collector plate arranged at the anode side end of the stacked body, an output terminal for outputting at least part of the collected electricity to the outside is provided in the vicinity of at least one of the anode exhaust gas exhaust hole, the cathode exhaust gas exhaust hole, and the medium supply hole. |

1. A fuel cell stack comprising:
a stacked body constituted by stacking a plurality of power generating elements, which contain an electrolytic membrane and electrocatalytic layers arranged respectively at the anode side and the cathode side of the electrolytic membrane, via a separator for providing a flow path for supplying reaction gas to the electrocatalytic layer, and collector plates arranged at both ends of the stacked body, for collecting electricity generated by the stacked body and outputting it to the outside, wherein on the separator and the collector plate are formed an anode gas supply hole for supplying reaction gas to the anode, a cathode gas supply hole for supplying reaction gas to the cathode, an anode exhaust gas exhaust hole for exhausting anode exhaust gas, a cathode exhaust gas exhaust hole for exhausting cathode exhaust gas, a medium supply hole for supplying into the stacked body a medium for maintaining the temperature of the stacked body at an approximately fixed level, and a medium exhaust hole for exhausting the medium from the stacked body, and at the anode side collector plate arranged at the anode side end of the stacked body, an output terminal for outputting at least part of the collected electricity to the outside is provided at a position closer to the anode exhaust gas exhaust hole, the cathode exhaust gas exhaust hole, and the medium supply hole than the anode gas supply hole, the cathode gas supply hole, and the medium exhaust hole. |
