FUEL CELL SYSTEM

摘要

PURPOSE: A fuel cell system is provided to generate electricity in both electrodes by using exhaust gas, and not to need additional fuel for the same, thereby improving generation efficiency. CONSTITUTION: A fuel cell system comprises an electricity generator(100) consisting of a cathode(110) generating carbonate by reacting oxygen and carbon dioxide and an anode(120) generating exhaust gas and electricity by reacting hydrogen and the carbonate; an engine part(300) generating power by receiving the exhaust gas; and an air separation part(400) separating air flowed into to oxygen and nitrogen. Oxygen generated from the air separation part is supplied to the engine part. A pre-mixing member(310), which mixes the exhaust gas and the oxygen before ignition, is in the engine part.
