FUEL CELL STACK |
| 摘要 |
A fuel cell stack includes cell units stacked on one another and each including a membrane electrode assembly and two separators defining gas passages on both sides of the membrane electrode assembly, a cooling fluid passage for flowing a cooling fluid provided between the separators of each adjacent two of the cell units, and a displacement absorber provided in the cooling fluid passage. The displacement absorber includes elastic protrusions provided in an array and configured to elastically absorb a displacement of the cell units in a stack direction, and flow-spread preventing protrusions provided in an array and configured to prevent the cooling fluid from flowing out of an active area. |

1. A fuel cell stack comprising:
cell units stacked on one another and each including a membrane electrode assembly and two separators defining gas passages on both sides of the membrane electrode assembly; a cooling fluid passage for flowing a cooling fluid provided between the separators of each adjacent two of the cell units; and a displacement absorber provided in the cooling fluid passage, wherein the displacement absorber comprises: elastic protrusions provided in an array and configured to elastically absorb a displacement of the cell units in a stack direction; and flow-spread preventing protrusions provided in an array and configured to prevent the cooling fluid from flowing out of an active area. |
