Abstract

A fuel cell system includes a first electrolyte-electrode assembly which comprises a hydrogen ion-conductive electrolyte layer, and a fuel electrode and a hydrogen-generating electrode that sandwich the electrolyte layer; a second electrolyte-electrode assembly which comprises a hydrogen ion-conductive electrolyte layer, and a fuel electrode and an oxidant electrode that sandwich the electrolyte layer; a fuel supplying means for supplying a liquid or gas fuel to the fuel electrode of the first electrolyte-electrode assembly; a means for applying to the fuel electrode of the first electrolyte-electrode assembly a potential which is positive to the hydrogen-generating electrode; and a means for supplying to the fuel electrode of the second electrolyte-electrode assembly hydrogen generated in the hydrogen-generating electrode.
