TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The apparatus further comprises a heat and electricity demand reactors controllably linked to the inlet and outlet flow diverters. It further comprises electricity storage device (battery) in electrical communication with the cell and a membrane separation system (36) having hydrogen permeable membrane that has a film consisting of palladium (Pd), Pd-silver (Ag), Pd-niobium (Nb), or Pd-tantalum (Ta). The membrane further comprises a gas permeable support consisting of ceramic, porous stainless steel, Ta, Nb, zirconium (Zr), and/or vanadium (V).The apparatus has hydrogen storage medium having metal capable of forming metal hydride, and methanation ozone defining a catalyst retention space. It also has a furnace having combustion gas burner inlet in communication with heat exchanger outlet, and a mechanism for detecting demand for furnace heat and is controllably linked to on-off valve.Preferred Device: The fuel cell is a proton exchange membrane fuel cell. The cracking reactor is within heating chamber.Preferred Conditions: The cracking condition is at 400-800degreesC and 0.5-5 atm absolute. The gas hourly space velocity is 10-100000/hour. The carbon loading endpoint is 1-500 wt.% carbon and the hydrogen concentration in the effluent stream is greater than 10 vol.%. The regeneration condition is 500-1000degreesC and 0.5-5 atm absolute. The gas hourly space velocity is 1000-100000/hour and regeneration endpoint is less than 5 wt.% carbon. Ta is 0.5-3 hours and T1 is 1-10 minutes.Preferred Method: A first duration of carbon deposition is longer than that of a second one and a first duration of regeneration is longer than that of a second one. Carbon monoxide and hydrogen in the effluent are converted to methane in presence of methanation catalyst to yield treated effluent for passage to the cell. There is combustion of a low temperature regeneration effluent in the furnace to provide heat. A high temperature regeneration effluent is mixed with a furnace fuel for combustion. A reactor of carbon oxides is purged from the regeneration cycle by flowing the fuel gas to the reactor to yield a purged element for combustion in the furnace.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Materials: The metal is titanium bound with an inert support from alumina, silica, zirconia, titania, and/or clays. The regenerant stream comprises oxygen gas containing stream or water containing stream. The catalyst comprises iron or nickel metal dispersed on an inorganic metal carrier consisting of alpha alumina, gamma alumina, theta alumina, cordierite, silica, magnesia, zirconia, and/or titania.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The hydrocarbon fuel is consists of natural gas, methane, ethane, propane, and/or butane.
