Abstract
A fuel cell using biogas as a fuel is provided, in which the fuel cell is supplied with a first gas required at a fuel electrode and a second gas required at an air electrode, which are separated from the biogas by a selective permeation method using a separation membrane of a gas-purification separation unit, and supplies gas discharged from the fuel cell along with the biogas to the gas-purification separation unit.
