摘要： A polymer electrolyte fuel cell comprises an electrolyte membrane-electrode assembly, a pair of conductive separator plates sandwiching the electrolyte membrane of the electrolyte membrane-electrode assembly, and a pair of sealing means sealing between the electrodes of the electrolyte membrane-electrode assembly and the separator plates. The pair of sealing means is constituted by combination of a flat sealing member having a flat portion in flat contact with the electrolyte membrane and of a linear sealing member having a rib in linear contact with the electrolyte membrane, and at least part of the rib is in the form of falling in the direction to the electrode when the electrolyte membrane, the pair of electrodes and the pair of separator plates are stacked to be cramped.
This makes it possible for the fuel cell to have an excellent sealing property and a stable output characteristic.

摘要： An electrode of solid polymer electrolyte fuel cells is produced by a step of preparing a mixed liquid containing an organic solvent, a noble metal catalyst- (3) supporting carbon powder (4) and a colloid of a solid polymer electrolyte having a particle size of 1 nm or more and less than 400 nm, said colloid being adsorbed to the carbon powder and a step of forming an electrode by coating said mixed liquid on one side of a gas-diffusible layer (9). According to the present invention, the solid polymer electrolyte (5) is surely adsorbed to the surface of the catalyst and thus a wide reaction area can be secured. Furthermore, thickness of the solid polymer electrolyte layer can be controlled to one in which hydrogen and oxygen can be easily diffused.

摘要： By using a gas diffusion layer for a fuel cell comprising a fabric comprising a warp thread and a weft thread which are made of carbon fiber, wherein the distance X between adjacent intersections where the warp and weft threads cross each other and the thickness Y of the fabric satisfy the equation: 1.4 ≦ X/Y ≦ 3.5, the present invention reduces the surface asperities of the substrate and prevents a micro short-circuit resulting from the piercing of the polymer electrolyte membrane of the fuel cell by the carbon fibers of the fabric so as to improve the characteristics of the fuel cell.
In order to further prevent the piercing of the polymer electrolyte membrane by the carbon fibers of the gas diffusion layer substrate, the rough surface of the carbon fabric is smoothed by:(1) applying a clamping pressure of 1 to 20 kgf/cm 2 to the contact area between each electrode and each conductive separator plate of the fuel cell; or (2) heating the gas diffusion layer surface before the gas diffusion layer is disposed onto the polymer electrolyte membrane.
