Title:
FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/167764
Kind Code:
A1
Abstract:
A fuel cell system comprises: a fuel cell (20) for generating power by a power generation reaction using a fuel supplied to an anode (22) and cathode air supplied to a cathode (24); a cathode air heat exchanger (44) for exchanging heat between cathode exhaust gas that is the air after being used in the fuel cell (20) and air to be supplied to the cathode (24) and transferring part of the thermal energy possessed by the cathode exhaust gas to the air; a desulfurization unit (46) for removing sulfur components from a supplied raw material; and a reformer (12) for generating a reformed gas serving as the fuel from a vapor and the raw material from which the sulfur components have been removed by the desulfurization unit (46). At least the cathode exhaust gas from which the part of the thermal energy is lost by the heat exchange in the cathode air heat exchanger (44) is supplied to the desulfurization unit (46) to heat the desulfurization unit (46) by the thermal energy possessed by the cathode exhaust gas.
