Abstract:
A solid oxide fuel cell (SOFC) system including a steam reformer, a hydrogen purification system, a pre-reformer, and a solid oxide fuel cell.

Claim (Index 1):
A solid oxide fuel cell (SOFC) system comprising:\n a steam reformer, the steam reformer comprising:\n catalytic reactor tubes, where the catalytic reactor tubes are operable to receive steam and a hydrocarbon feed and are operable to convert hydrocarbons of the hydrocarbon feed into hydrogen to produce a reformer syngas, the reformer syngas comprising hydrogen; and \n a combustion chamber, where the combustion chamber is thermally coupled to the catalytic reactor tubes, is operable to receive the hydrocarbon feed, an oxygen feed, and an anode exhaust gas, and is operable to produce a flue gas, the flue gas comprising carbon dioxide; \n a hydrogen purification system, where the hydrogen purification system is operable to receive the reformer syngas and is operable to produce a purified hydrogen gas and an off-gas stream, the off-gas stream comprising methane; a pre-reformer, where the pre-reformer is operable to receive the hydrocarbon feed and the anode exhaust gas and is operable to produce a pre-reformer syngas, the pre-reformer syngas comprising methane; and a solid oxide fuel cell, where the solid oxide fuel cell is operable to electrochemically convert methane and water into hydrogen and carbon oxides to produce electrical power and where the solid oxide fuel cell comprises an anode side,\n where the anode side is operable to produce the anode exhaust gas, the anode exhaust gas comprising hydrogen and carbon oxides, and comprises an anode side inlet,\n where the anode side inlet is fluidly coupled to the hydrogen purification system and the pre-reformer and is operable to receive an anode feed, the anode feed comprising a mixture of the off-gas stream and the pre-reformer syngas.
