SOLID OXIDE FUEL CELL SYSTEM

摘要

A solid oxide fuel cell system (90) is provided with: a reformer (10); a solid oxide fuel cell (12) that generates electricity using a hydrogen containing gas supplied to an anode (14) from the reformer and air supplied to a cathode (16); a heat radiator (17) that radiates heat from either or both of anode off gas and combustion exhaust gas obtained by combustion of the anode off gas and generates condensed water; a condensed water circulation path (20) in which condensed water supplied by the heat radiator circulates; a condensed water tank (22) that is provided in the condensed water circulation path and retains the condensed water; a condensed water pump (24) that is provided in the condensed water circulation path and circulates the condensed water; and a condensed water/off gas heat exchanger (26) that is provided in the condensed water circulation path and carries out heat exchange between the condensed water and the off gas exhausted from the solid oxide fuel cell. At least part of water supplied to the reformer is condensed water.
