Abstract
A fuel cell-purposed separator has a gas channel that includes a plurality of stages connected via turnaround portions. A bypass is provided which connects an upstream-side stage to a downstream side stage. After flowing through the downstream-side stage, a gas is let out of a gas outlet. The fuel cell-purposed separator thus constructed curbs a gas concentration drop on the downstream side in the gas channel.
Claims11
A fuel cell-purposed separator comprising:
- a gas passage having a plurality of stages that are connected via a turnaround portion;
- and
- a bypass that connects an upstream-side stage of the gas passage to a downstream-side stage of the gas passage and that causes a gas that flows in via a gas inlet of the bypass to flow out of a gas outlet.
A fuel cell-purposed separator comprising:
- a gas passage having a plurality of turnaround portions;
- and
- a bypass that connects a most upstream-side turnaround portion of the gas passage to a most downstream-side turnaround portion of the gas passage,
- wherein a gas inlet to the separator and a gas outlet from the separator are located at a same side of the separator.
