| 摘要 |
A separator for a fuel cell includes a thin metal plate, protrusions that are formed on the metal plate to be close to each other, and gas passages formed by the protrusions. Each gas passage has a first opening corresponding to an inlet and a second opening corresponding to an outlet. The gas passages include a first gas passage, which has a relatively low pressure loss of gas flow, and a second gas passage, which has a relatively high pressure loss of gas flow. The area of the first opening of the first gas passage is set to be smaller than the area of the first opening of the second gas passage. |
