ABSTRACT:
A hydrocarbon (hydrogen)/air aerogel catalyzed carbon electrode fuel cell system comprising an acid electrolyte filled; steam hydrocarbon catalytic reformer with a heater and operating to receive and reduce hydrocarbons and water into a reformed gas of hydrogen and carbon dioxide gases; a centrifugal gas-separator device receiving reformed gas from the reformer and operating to separate the hydrogen and carbon dioxide gases of the reformed gas and delivering them separately; a fuel cell comprising a micro porous catalyzed-carbon aerogel anode electrode fed with hydrogen gas delivered by the gas separator, a micro porous catalyzed-carbon aerogel cathode electrode fed with oxygen from ambient air, and, a micro porous cation-filled silica hydrogel electrolyte separator between the anode and cathode electrodes; a hydrocarbon fuel supply delivering hydrocarbon fuel to the reformer; a combustion fuel supply selectively delivering hydrocarbon and hydrogen gas to the heater; and, a water supply receiving water produced in the fuel cell by fuel cell reaction and delivering it to the reformer.
