Process for the production of electrical energy in an internal reforming high temperature fuel cell

摘要

A process for producing electrical energy in an internal reforming, high-temperature fuel cell. Steam reforming of a carbonaceous feed gas takes place in the presence of a steam-reforming catalyst in heat-conducting relationship with electrochemical reactions in the fuel cell. The steam reformed feed gas is electrochemically reacted in an anode compartment of the fuel cell. The process is improved by controlled addition of a gaseous, sulfur-containing compound to the carbonaceous feed gas in an amount sufficient to obtain a sulfur coverage on the steam reforming catalyst of between 0.1 to 0.9.
