摘要:
A method for activating a direct oxidation fuel cell including an anode, a cathode, and a proton-conductive electrolyte membrane interposed between the anode and the cathode is provided. The anode and the cathode each have a catalyst layer on a face in contact with the proton-conductive electrolyte membrane. This method activates the fuel cell by passing a current through the fuel cell from an external power source, with the positive electrode and the negative electrode of the external power source connected to the anode and the cathode of the fuel cell, respectively, while supplying an organic fuel and an inert gas to the anode and the cathode, respectively.

A fuel cell system includes: a fuel cell including an anode, a cathode, and an electrolyte interposed between the anode and the cathode; and a purifying apparatus including a catalyst layer that purifies an effluent discharged from the anode. The purifying apparatus has a porous sheet including the catalyst layer and two flow paths disposed on both sides thereof. One of the flow paths has an inlet into which the effluent discharged from the anode is introduced, and the other flow path has an inlet into which air is introduced and an outlet. The effluent discharged from the anode is passed through the porous sheet for purification and then discharged from the outlet.

摘要:
A fuel cell system includes: a dilute tank that stores an aqueous solution of liquid fuel and supplies the solution to the anode of a fuel cell; a fuel tank connected to the dilute tank via a first controlling section; a water tank connected to the dilute tank via a second controlling section; and controlling means including a current detector which measures the amount of the fuel consumed by the fuel cell from the amount of power generation. The controlling means controls the first controlling section based on the measured amount of fuel consumption and further includes correcting means for measuring a component of a gas discharged from the cathode, calculating the amount of the fuel which has crossed over from the anode to the cathode based on the measured component, and correcting the measured amount of fuel consumption based on the calculated amount of fuel crossover.
