A fuel cell system has a membrane electrode composite including an anode, cathode and an electrolyte membrane sandwiched between the anode and the cathode. A lyophobic porous member is located adjacent to the anode, and an anode channel plate is also located adjacent to the porous member. A gas recovery channel and a fuel supply channel are formed in the anode channel plate, gas generated at the anode side is recovered in the gas recovery channel and a liquid fuel is supplied to the anode through the fuel supply channel. The generating system also includes a circulating system along which the fuel circulates, and a fuel supply section that supplies fuel to the circulating system.
