ABSTRACT:
A fuel cell generator including a tubular solid electrolyte partition having ion conductivity, a fuel electrode provided on the inner peripheral surface or the outer peripheral surface of the tubular solid electrolyte partition, an air electrode provided on the tubular solid electrolyte partition at the opposite side of the fuel electrode, a conductive fuel gas supply tube and a conductive oxidizing gas supply tube, at least one of these tubes being arranged in an inner space of the tubular solid electrolyte partition. Multipoint contact current collectors are made to contact with electrode surfaces of the fuel electrode and the air electrode substantially over the entire surface thereof, respectively and electrically connect between the conductive fuel gas supply tube and the fuel electrode or between the conductive oxidized gas supply tube and the air electrode.
