A fuel cell has unit cells wherein gas discharged from an oxidizer electrode in one unit cell and gas discharged from a fuel electrode in other adjacent unit cell are merged in and charged through a discharge flow passage provided outside these unit cells. The discharge flow passage is shared by the oxidizer electrode in the one unit cell and the fuel electrode in the other unit cell. A flow of the gas discharged from the oxidizer electrode is utilized to efficiently exhaust the gas discharged from the fuel electrode.
