Abstract
A fuel cell apparatus is capable of quickly heating a solid electrolyte to a proper temperature in order to perform effective electric power generation. The apparatus includes a fuel cell (1) for generating electric power by cell reacting a fuel gas on an anode-(3) side with oxygen on a cathode-(4) side. The fuel cell (1) includes a solid electrolyte (2) formed of a porous mass and uses a differential pressure to cause the fuel gas on the anode-(3) side to permeate through the solid electrolyte to the cathode-(4) side. The solid electrolyte (2) is heated by combustion reaction of the fuel gas permeated through the solid electrolyte (2) and mixed with the oxygen.
