20130059226 | MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR GAS DIFFUSION LAYER OF FUEL CELL, AND FUEL CELL - According to a manufacturing method for a fuel cell, an insulating member having a plurality of communication holes therein is disposed on a side of a gas diffusion layer, which is formed by stacking a layer made of a carbon fiber and a water-repellent layer, where the water-repellent layer is provided, the gas diffusion layer and the insulating member are sandwiched by a pair of electrodes, and a pair of contact pressure plates are disposed on respective rear surfaces of the pair of electrodes so as to sandwich the pair of electrodes so that the gas diffusion layer is pressurized by the pair of contact pressure plates. When a voltage is applied to the pair of electrodes while maintaining the pressurized state, an electric current flows through a protrusion portion of a carbon fiber which comes in contact with the electrode on the water-repellent layer side via the communication holes of the insulating member, so that the protrusion portion of the carbon fiber is burned and removed by Joule heat. When it is detected that no electric current flows between the electrodes, application of a voltage to the pair of electrodes is stopped, and the pressure in the pressurized state is decreased to a normal pressure state. | 03-07-2013 |
20130089808 | FUEL CELL, AND METHOD OF MANUFACTURING A FUEL CELL - A fuel cell includes a separator and a power generating body. The separator and power generating body are laminated each other. The power generating body is equipped at least with an electrolyte membrane. The fuel cell comprises: a sealing part that seals reaction gas supplied for electrochemical reactions at the fuel cell between the power generating body and the separator at an outer circumference part of the fuel cell, wherein a convex part and a recess are fit together in the sealing part. The convex part is formed projecting in the lamination direction on one of the power generating body and the separator, and the recess is formed recessed in the lamination direction on the other of the power generating body and the separator. At least one of the convex part and the recess is formed with a polymer material that expands with moisture absorption. | 04-11-2013 |
