A fuel cell power system having at least one fuel cell stack, at least one fuel processor in fluid communication with the at least one fuel cell stack and heat exchangers for transferring heat between the at least one fuel cell stack and the at least one fuel processor in which the at least one fuel cell stack and the at least one fuel processor are circumferentially surrounded by a plurality concentric heat exchanger shell assemblies.

Thermally integrated fuel cell power system

A method for removing a condensable component from a process stream in which a first side of a permselective membrane is contacted with the process stream in which is disposed the condensable component. The condensable component is passed through the permselective membrane to a second side of the permselective membrane, forming a condensable permeate. The condensable permeate is then contacted with a liquid stream having a liquid form of the condensable permeate, forming a condensed permeate. The condensed permeate may then be returned to the process which generated the process stream.

A molten alkali metal carbonates fuel cell porous anode of lithium ferrite and a metal or metal alloy of nickel, cobalt, nickel/iron, cobalt/iron, nickel/iron/aluminum, cobalt/iron/aluminum and mixtures thereof wherein the total iron content including ferrite and iron of the composite is about 25 to about 80 percent, based upon the total anode, provided aluminum when present is less than about 5 weight percent of the anode. A process for production of the lithium ferrite containing anode by slipcasting.

Carbonate fuel cell anodes

Molten carbonate fuel cell anodes incorporating a sulfur tolerant carbon monoxide to hydrogen water-gas-shift catalyst provide in situ conversion of carbon monoxide to hydrogen for improved fuel cell operation using fuel gas mixtures of over about 10 volume percent carbon monoxide and up to about 10 ppm hydrogen sulfide.

An electrochemical separation of oxygen from oxygen containing gaseous mixtures, such as air, using an oxygen containing molten inorganic salt electrolyte retained in a porous matrix between two gas porous catalytic electrodes wherein oxygen is separated from the gaseous mixture when electrical potential is applied across the electrodes providing movement of non-metallic oxygen containing ion from the cathode to the anode.

Electrochemical separation of oxygen

An electrochemical separation of oxygen from oxygen containing gaseous mixtures, such as air, using a molten nitrate salt electrolyte retained in a porous matrix between two gas porous catalytic electrodes wherein oxygen is separated from the gaseous mixture when electrical potential is applied across the electrodes providing movement of ionic NO.sub.3 - from the cathode to the anode.

An electrically rechargeable anionically active reduction-oxidation electric storage-supply system and process is disclosed using a sodium or potassium sulfide-polysulfide anolyte reaction and an iodide-polyiodide, chloride-chlorine or bromide-bromine species catholyte reaction. The catholyte and anolyte are separated by an ion selective membrane permeable to positive sodium and potassium ions and substantially impermeable to negative bromide, chloride, iodide, sulfide and polysulfide ions. A flowing electrolyte system is disclosed with external electrolyte storage vessels. The apparatus and process provide an electrically rechargeable anionically active reduction-oxidation system in which the electrolytes may be maintained at near neutral or slightly basic pH, with virtually no parasitic side reactions upon charging, such as hydrogen or oxygen evolution, and the disclosed storage and supply system provides higher energy densities than referenced prior art systems.

Electrically rechargeable anionically active reduction-oxidation

A process for electrolytic recovery of zinc wherein metallic zinc is deposited at the cathode while the anode is depolarized through oxidation of iodide ions to iodine, avoiding oxygen evolution at the anode. The iodide ions are chemically regenerated by extracellular oxidation of sulfur dioxide with water to produce iodide ions and hydrogen ions for recycle to the anode compartment. The utilization of iodide ions in the depolarization of the anode results in obtaining good deposits of elemental zinc at high faradic efficiencies resulting in energy saving of 30 to 40 percent over conventional electrowinning of zinc.

Depolarized electrowinning of zinc

A lead-acid battery having a positive electrode with an electrically conducting current collector bus plate, a honeycomb matrix structure extending from at least one side of the bus plate forming multiple positive active material compartments and an acid ion porous retainer means adjacent the open ends of the material compartments, the compartments containing positive active material having lead oxide reactive material and an electronic conductive additive within an acid ion porous structure. The electronic conductive additive increases the electronic flow from the reaction site in the positive active material to the current collector bus plate. This invention provides an improved positive active material with an electronic conductive additive. The positive active material, positive electrodes and lead-acid batteries of this invention provide high energy densities and high cycle lives suitable for use in electric vehicles.
