The oxygen electrode operates through the mechanism of redox couples which uniquely provide multiple degrees of freedom in selecting the operating voltages available for such fuel cells. Such oxygen electrodes provide the fuel cells in which they are used a “buffer” or “charge” of oxidizer available within the oxygen electrode at all times.

Abstract: A fuel cell utilizing parallel flow of a hydrogen stream, an oxygen stream, and an electrolyte solution with respect to the electrodes, while maintaining mechanical support within the fuel cell. The fuel cell contains multiple layers of electrodes which absorb and react hydrogen and oxygen. The fuel cell is designed to maintain mechanical support within the fuel cell while the electrodes expand and contract in response to the absorption of oxygen and hydrogen. The design of the fuel cell provides a substantially more compact design by not requiring space to allow for the expansion and contraction of the electrodes within the fuel cell.

Abstract: A method and system for electrochemically purifying an impure stream of hydrogen. Hydrogen is absorbed into a gas diffusion anode from the impure hydrogen stream and oxidized to form hydrogen ions and electrons which are released into an alkaline solution. An electrolytic cathode also positioned in the alkaline solution decomposes water to form hydrogen and hydroxyl ions which combine with the hydrogen ions to maintain equilibrium of the system.
