SOLID OXIDE FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell system capable of downsizing a reformer which is heated by combustion exhaust gas.SOLUTION: A solid oxide fuel cell system comprises: a solid oxide fuel cell in which power is generated using hydrogen-containing gas supplied to an anode 12 and air supplied to a cathode 14; an anode off-gas heat radiator 16 which collects condensed water by radiating heat of anode off-gas exhausted from the anode; a first heat exchanger 18 for exchanging heat between anode off-gas before supplied to the anode off-gas radiator and anode off-gas after exhausted from the anode off-gas radiator; a combustor 20 for combusting anode off-gas which is exhausted from the anode off-gas radiator and then further passed through the first heat exchanger; and a reformer 22 in which hydrogen-containing gas is generated by using a raw material and condensed water supplied from the anode off-gas radiator and the hydrogen-containing gas is supplied to the anode.
