    摘要: A fuel cell has a plurality of unit cells each including electrodes sandwiching an electrolyte membrane in-between, and a plurality of separators (3) each arranged between the unit cells. Each separator (3) has a plurality of contact lugs (65, 75) facing the electrodes and contacting the electrodes at pre-set contact widths and a plurality of fluid ducts (6a, 7a) each having a space between neighboring ones of the contact lugs (65, 75) as a duct width. The contact width of the contact lugs 65 (75) on a side closer to a fluid outlet is set smaller than that of the contact lugs 65 (75) on a side closer to a fluid inlet. Diffusion of an active material in an active material containing fluid into the inside of electrodes on a downstream side of a fluid duct, that is on a side closer to a fluid outlet, is facilitated.

    摘要: A fuel-cell stack is provided wherein an insulating resin layer having good electrical insulation characteristics is inserted between a terminal and end plate, so that an insulating plate is discarded so as to make the same more lightweight and downsized. It comprises a battery-cell group wherein a plurality of battery cells and separators are arranged; and terminal plates 1 and end plates 3 that are arranged on each end portion of the battery-cell group. The end plates 3 are formed as metal plate members having surfaces 31 opposing to the terminal plates 1. A polyimide film 35 is formed as an insulating resin layer at least on the opposing surface 31 of the end plate 3 for electrically insulating between the end plate 3 and terminal plate 1 by an electro-deposition coating method.

    摘要: For use in a fuel cell, constituted by plural cells, a separator that can reduce fluctuations in electromotive force across respective cells. An electrically conductive member 3, as a separator, and a processing electrode 16, having patterned electrode projections 20, are immersed in an electrolytic solution facing each other. Current is fed between member 3 and electrode 16 for electrolytic processing to dissolve the portion of the member 3 facing projections 20, thus forming a gas path 30 having a surface roughness Rz on this bottom surface 30e not larger than 1 &mgr;m. Using the separator having the gas path with extremely smooth bottom surface, the gas flow in each cell proceeds in a reduced fluctuation to reduce fluctuations in the electromotive force.

    摘要: A method for producing a separator integrated with a gas flow channel of fuel cells efficiently at low costs without deteriorating processing accuracy and the like. A plane-facing electrode nozzle 30 is placed oppositely to the face to be processed, which is partially covered with a mask M, of base material B of a separator. While feeding electricity to the electrode nozzle 30 and the base material B of a separator, an electrolytic solution is injected and fed from the side of the electrode nozzle 30 to the face to be processed of the base material B from a direction that is almost perpendicular to the face. Thereby, the unmasked portion undergoes electrolytic etching with the electrolytic solution lying between the face to be processed and the electrode nozzle 30 to form recessed portions for making a gas flow channel.
