SULFUR-TOLERANT HIGH-TEMPERATURE FUEL CELL SYSTEM WITH INTERNAL WATER-GAS SHIFT CATALYST

摘要

A fuel cell system is provided, including a fuel cell stack with a plurality of cathodes (30) and anodes (34), wherein an oxidizing gas containing oxygen is feedable to the stack on the cathode side and a fuel gas is feedable to the stack on the anode side, and a reformer for generating the fuel gas from a fuel. The fuel cell stack includes a catalytically active material (42) which is arranged in the anode-side regions such that the fuel gas flows through the material upstream of the anode (34), wherein the catalytically active material catalyzes the reaction of carbon monoxide and water to carbon dioxide and hydrogen.
