FUEL CELL SYSTEM HAVING WATER SUPPLY APPARATUS FOR REFORMER

摘要

A fuel cell system is provided to effectively condense, in a condenser, water vapor generated from a reforming step of hydrogen-containing fuel in a reformer and feed the condensed water to a reformer without operating a water pump, etc. The fuel cell system comprises: an electricity generator part(10) which generates electricity by an electrochemical reaction of hydrogen and oxygen; an air supply part which feeds oxygen-containing gas to the electricity generator part(10); a reformer(52) which produces reformed gas containing, as a main component, hydrogen to be supplied to the electricity generator part(10); and gas-liquid separators(62) which are provided between the electricity generator part(10) and the reformer(52) and capture water vapor to be generated from a production step of the reformed gas.
