摘要： High-purity nitrogen gas is generated by reducing at least the residual oxygen content of at least the cathode exhaust gas stream of a fuel cell device. The oxygen reduction is achieved either by controlling the passage of an oxidant gas through the cathode side of the fuel cell device in such a manner as to increase the oxygen utilization at the cathode side of the fuel cell device relative to the optimum electric power generation operating conditions of the fuel cell device, or by removing most of the residual oxygen from the cathode exhaust gas stream exhausted from the cathode side of the fuel cell device, while maintaining both oxygen and nitrogen contained in the cathode exhaust gas in their gaseous states throughout, or both. Moreover, anode exhaust gas can be reacted in a reformer burner with a reduced amount of excess oxygen and/or the reformer burner exhaust gas can be purified to remove combustion products and/or oxygen therefrom.

摘要： An arrangement for replenishing hydrogen consumed in a fuel cell device includes a reaction vessel that contains a quantity of a material that releases hydrogen on contact with water in a highly exothermic reaction. A hydrogen-containing gaseous medium is passed through the material quantity under conditions resulting in removal of heat from the material quantity by convection at a heat removal rate sufficient to maintain a temperature differential between an inlet portion and an outlet portion of the reaction vessel below a predetermined level. This includes recirculating a portion of the gaseous medium from the outlet portion to the inlet portion and cooling at least the recirculated portion. Water vapor is added to the recirculated gaseous medium portion at a rate commensurate with that at which hydrogen is being consumed in the fuel cell device for such added water vapor to exothermically react with the solid material, whereas the remainder of the gaseous medium is supplied from the outlet portion to the fuel cell device.

摘要： The cell stack can be operated as a fuel cell stack or as an electrolysis cell stack. The stack consists of a series of alternate fuel cell subassemblies with intervening electrolysis cell subassemblies, and interspersed cooling plates. The water produced and consumed in the two modes of operation migrates between adjacent cell subassemblies. The component plates are annular with a central hydrogen plenum and integral internal oxygen manifolds. No fluid pumps are needed to operate the stack in either mode.

摘要： A seal material especially adapted for phosphoric acid fuel cell stack sealing is described comprising an unfilled, unoiled high molecular weight polytetrafluoroethylene. Although the seal material is especially adapted as the regular seal around the plenums separating the oxygen and hydrogen gas inlets and outlets, it can also be used as a plenum or stack crack sealer. The material provides seal integrity and stability at temperatures in excess of 400.degree. F. (204.degree. C.)., e.g. 400.degree. F. to 450.degree. F. (204.degree. C. to 232.degree. C.), in a corrosive chemical environment at differential pressures above 50 psi (e.g. 50 psi to 80 psi). It can be used in electrochemical cells in general where high temperature, high pressure, corrosive environments prevail.

摘要： The effluent gas stream from anaerobic waste water treatment digesters is treated to remove trace amounts of hydrogen sulfide and other contaminants. The chemical equation involved relies on the reaction of hydrogen sulfide with oxygen to form water plus elemental sulfur. The removal system includes a variable control line for adding air to the effluent gas stream; a filter for removing solids, entrained liquids and bacteria from the oxygen-enriched gas stream; a blower for directing the filtered gas stream into a potassium promoted activated carbon bed wherein the above chemical reaction takes place; and sensors for measuring the content of oxygen and hydrogen sulfide at the entrance and exit of the activated carbon bed. When the hydrogen sulfide content of the exiting gas stream exceeds a predetermined level, the amount of air added to the gas stream is increased until the predetermined level of hydrogen sulfide is achieved in the exiting gas stream.
