Abstract:

An integrated dry gas fuel cell (IDG-FC) is provided. The IDG-FC includes at least one solid oxide fuel cell having an anode, a cathode and an electrolyte membrane disposed between the anode and the cathode. The IDG-FC further includes a conversion bed, where carbon dioxide gas is provided to the conversion bed to convert carbon monoxide gas from the carbon dioxide gas. Solid carbonaceous fuel is provided to the conversion bed to promote the gas conversion. The carbon monoxide is provided as fuel to the anode, and air is supplied to the cathode to provide oxygen for oxidation of the carbon monoxide at the anode to generate electric power. This new process does not require water, and supplies the oxygen required for the oxidation reaction through an ionically selective solid oxide electrolyte membrane.
