Abstract

Nickel solid oxide fuel cell anodes are unsuitable for operation with dry natural gas because of carbon deposition. Results from steady state and temperature programmed experiments over an alternative anode material, La0.8Ca0.2CrO3-x, indicate that both complete oxidation of methane and surface methane dissociation occur at temperatures above 500 degrees C. Negligible carbon deposition occurs during complete oxidation.
