Abstract

See full text

A method of operating a fuel cell system is provided. The fuel cell system may comprise one or more solid oxide fuel cells. One or more of the fuel cells may be operated in a fuel cell mode under an average current density of 100 to 1000 mA/cm2 for a period of at least five hundred hours. The method may further comprise operating at least one of the fuel cells in an electrolyzer mode under an average current density from 100 to 1500 mA/cm2, which may be applied for at least one hour. The ratio of the average current density in the electrolyzer mode to the average current density in the fuel cell mode may be at least one but no more than two and one-half.
