Abstract: The present invention provides a safe fuel cell system. The fuel cell system comprises a fuel cell device operating with an organic liquid fuel; a fuel cartridge for feeding the organic liquid fuel to the fuel cell device; a pump for feeding the organic liquid fuel in the fuel cartridge to the fuel cell device while diluting the fuel; an air pump for feeding air to the fuel cell device; and an adsorption unit for adsorbing harmful substances generated from a reaction in the fuel cell device. For discharging a gas from the system, the gas is flown through the adsorption unit for adsorption of harmful substances and then discharged from a vent.

Abstract: An object of the present invention is to provide a fuel cell capable of improving an output by reducing concentration polarization of a liquid fuel in an anode. The fuel cell comprises an anode and a cathode on both surfaces of an electrolyte membrane, supplies the liquid fuel to the anode, supplies an oxidant gas to the cathode, to react the liquid fuel with the oxidant gas and to generate power, wherein the anode comprises a gas diffusion layer constituted by filling a conductive porous support which is coated with a hydrophilic material with a conductive powder, and a catalyst layer.
