  • Publication number: 20090104499
    Abstract: 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.

  • Publication number: 20070072048
    Abstract: A fuel cell includes a fuel electrode, an oxidant electrode, a fuel supply port, and a porous material layer for transferring a liquid fuel from the fuel supply port to the fuel electrode. The porous material layer has different values of at least one of a porosity, a permeability and a tortuosity factor depending on the distance of a site of the porous material layer from at least one of the fuel supply port and the fuel electrode.
