FUEL CELL STACK |
| 摘要 |
A fuel cell stack is formed by stacking unit cells and each unit cell is formed by sandwiching a membrane electrode assembly between a pair of separators having depression parts and protrusion parts. A cooling liquid flow space is formed between the unit cells, and a displacement absorption member which absorbs displacement between the unit cells is disposed in the flow space. The displacement absorption member includes a spring function part having a free end and a fixed end, and an intrusion prevention means which prevents the free end of the spring function part from intruding into the depression part. A displacement absorption function between the unit cells is well maintained, while size reduction of the fuel cell stack is achieved. |
