SOLID OXIDE FUEL CELL SYSTEM

摘要

A solid oxide fuel cell system (90) including a reformer (10), a solid oxide fuel cell (12) configured to generate electric power by using a hydrogen-containing gas supplied from the reformer to an anode (14) and air supplied to a cathode (16), a heat radiator (17) configured to radiate heat from at least one of an anode off-gas and a combustion exhaust gas generated by combusting the anode off-gas to generate condensed water, a condensed water circulating passage (20) configured to circulate the condensed water supplied from the heat radiator, a condensed water tank (22) provided on the condensed water circulating passage and configured to store the condensed water therein, a condensed water pump (24) provided on the condensed water circulating passage and configured to circulate the condensed water, a condensed water/off-gas heat exchanger (26) provided on the condensed water circulating passage and configured to exchange heat between the condensed water and an off-gas discharged from the solid oxide fuel cell, and at least a part of the water supplied to the reformer is the condensed water.
