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.
