ABSTRACT:
An elongate fuel cell with anode and cathode chambers. A fuel supply delivers a hot fuel gas mixture of steam and methanol or methane to the anode chamber. A catalytic reformer in the anode chamber reforms the fuel gas to hydrogen and carbon dioxide. A hydrogen-permeable anode in the anode chamber is premeated by and diffuses the hydrogen to hydrogen ions and free electrons. A catalytic cathode in the cathode chamber receives hydrogen ions from the anode and is supplied with oxygen from the air. A di-electric, hydrogen-ion-permeable separator is positioned between the anode and the cathode to stop movement of electrons and permit movement of hydrogen ions therebetween. An external electric circuit is connected with and extends between the anode and cathode and conducts the free electrons from the anode to the cathode. The hydrogen ions, oxygen and electrons in the cathode react to produce the by-products, heat and water.
