NOVELTY - Proton exchange fuel cell comprises an anode (1), a cathode (3), a proton exchange material (5) that allows movement of hydrogen ions from the anode to the cathode, and a separate semiconductor arrangement (8) electrically connected to the anode and the cathode that allows movement of electrons from the cathode to the anode.    USE - For transport vehicles and for small to large stationary electric power generation units.    ADVANTAGE - The proton exchange fuel cell maintains good contact between the material and the anode and cathode electrodes, providing proper operation of the fuel cell under all operating conditions.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (a) a proton exchange fuel cell arrangement, comprising fuel cell elements as above, and a simple internal stacking of the fuel cell elements in a cylindrical cell container to allow high pressure hydrogen operation of the fuel cell arrangement; and    (b) a process to produce electricity from the reaction of hydrogen and oxygen to produce water in a proton exchange fuel cell arrangement as above, comprising pressurizing hydrogen at the outer catalyst surface (2,4) of the outer cylindrical anode; catalysing the hydrogen to hydrogen ions and electrons at the outer catalyst surface of the outer cylindrical anode where the electrons travel from the anode to an external electrical circuit through an electrical load to an inner cylindrical cathode through the semiconductor to the anode and the hydrogen ions travel through the anode, the proton exchange material between the anode and the cathode and the cathode to an inner catalytic surface of the cathode; and reacting the hydrogen ions with oxygen at the inner catalytic surface of the cathode to produce water.
