摘要： A polymer electrolytic fuel cell comprises a hydrogen-ion-conductive polymer electrolytic film, a pair of electrodes sandwiching the film, a conductive separator plate having a gas passage for supplying fuel to one of the electrodes, and a conductive separator plate having a gas passage for supplying an oxidizer to the other electrode. Conventionally, a conductive separator plate is made of a carbonaceous material, and therefore the costs such as the fabrication cost are difficult to reduce, and a metallic plate is used on trial instead of a carbonaceous plate. However the metallic plate is exposed to a hot oxidizing atmosphere, and as a result the metallic plate is corroded after a long use, lowering the power generation efficiency gradually. According to the invention, the metallic conductive separator plate is a type in which a conductive film containing conductive particles and glass is formed on a surface having a gas passage. Thus, the corrosion of the metallic plate is suppressed and the degradation of the power generation efficiency after long use is also suppressed.

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 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 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.
