    摘要： The invention provides a polymer electrolyte fuel cell device 1 comprising at least one fuel cell 10 having an anode, a cathode and a polymer electrolyte membrane provided between the anode and cathode, a combustion unit 3, a fuel gas pipe 4 for introducing therethrough the unreacted portion of a fuel gas discharged from the fuel cell 10 into the combustion unit 3, and an oxidizer gas supply manifold 2 for supplying oxidizer gas discharged from the combustion unit 3 to the cathode. By partly consuming the oxygen contained in an oxidizer gas supplied from outside, the combustion unit 3 burns the unreacted fuel gas and burns the impurities contained in the oxidizer gas. This feature prevents the polymer electrolyte membrane from drying, affords a high cell voltage without impairment and enables the device to achieve a higher overall efficiency than in the prior art.

    摘要： The object of the present invention is to provide fuel cell including a cell that is formed by sandwiching solid polymer membrane between an anode and a cathode that generates electricity with stability and high performance by evenly moistening the solid polymer membrane. For this purpose, in a gas diffusion layer 24, which is positioned adjacent to a cathode catalyst layer 22, the content of fluororesin in an area on the side of the entrance for the oxidizer is set to be higher than in another area on the side of the exit so that the water repellency in the entrance side area is higher than in the exit side area. As a result, a water permeation suppressing part 24A, where the water permeability is relatively low, is formed in the area on the entrance side, while a water permeable part 24B, where the water permeability is relatively high, is formed in the area on the exit side.

    摘要： A cell unit for use in fuel cells of the type using an electrode portion having an anode formed of a plate or film on one surface of an electrolyte and a cathode formed of a plate or film on the other surface. An anode side plate of the invention has stepped portions to form recesses which accommodate the electrode and provide an anode side chamber facing the anode. A cathode side plate having a cathode side chamber facing the cathode is also accommodated in the recessed portions of the anode side plate. A fuel supply manifold and a fuel discharge manifold can extend through the stepped portions. Use of such cell units reduces the number of seal members required between fuel or oxidant manifolds when cell units are stacked to form a fuel cell stack. Such reduction in seal members simplifies fabrication of the units and renders the cell unit easier to maintain and repair.
