Patent ID: 7824812

Claim:
A fuel cell system comprising: a fuel cell including at least one unit cell comprising an anode, an anode-side flow channel for supplying a fuel to said anode, a cathode, and a cathode-side flow channel for supplying an oxidant to said cathode; a fuel supply path and an oxidant supply path for supplying said fuel and said oxidant to said anode-side flow channel and said cathode-side flow channel, respectively; an anode-side discharge path and a cathode-side discharge path for discharging an effluent from said anode and an effluent from said cathode, respectively, said anode-side discharge path and said cathode-side discharge path being in fluid communication with a fuel outlet of said anode-side flow channel and an oxidant outlet of said cathode-side flow channel, respectively; and a gas-liquid separator for catalytically purifying said effluent from said anode and said effluent from said cathode in order to collect liquid, said gas-liquid separator being connected to said anode-side discharge path and said cathode-side discharge path.
