TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: The proton exchange material is fused to the anode and the cathode using a process comprising gluing, welding, brazing, or soldering. The proton exchange material is held between the frusto-conical inner surface and the frusto-conical outer surface. Preferred Component: The separate semiconductor arrangement comprises a semiconductor bridge, a separate semiconductor layer between the anode and proton exchange material or between the proton exchange material and the cathode. The anode comprises a frusto-conical surface on an inner surface. The cathode comprises a frusto-conical surface on an outer surface that matches the frusto-conical inner surface of the anode. The proton exchange fuel cell arrangement further comprises a mechanism that supplies pressurized hydrogen to the anode; a manifold within the cylindrical cathode that supplies air or oxygen to each of the fuel cell elements; a mechanism that provides good contact between the oxygen or air and the cathode surface; a first manifold within the cylindrical cathode that supplies air or oxygen to each of the fuel cell elements; and a second manifold within the cylindrical cathode that removes waste products from each of the fuel cell elements. The catalytic surface of the anode is the angled face engaged against the proton exchange material where impurities in the hydrogen do not poison the catalytic surface. Preferred Function: The anode has a catalytic surface that catalyses hydrogen-to-hydrogen ion. The anode has a catalytic surface engaged against the proton exchange material. Preferred Material: The cathode and anode are formed from material that allows easy passage of hydrogen ions or protons. Preferred Condition: The hydrogen is at a pressure of less than or equal to 333 bars at the anode. The oxygen is provided at a pressure of less than or equal to 10 bars at the cathode. The proton exchange fuel cell arrangement is operated at a temperature of less than or equal to 250degreesC. The anode is permeable to hydrogen.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The anode catalytic surface is fine platinum. The cathode has a catalytic surface comprising platinum or nickel (preferably platinum). The cathode and anode are formed from carbon, metal hydrides, metal carbides or their alloys (preferably carbon or metal hydrides).
