摘要： PROBLEM TO BE SOLVED: To provide a fuel cell and a separator for the fuel cell advantageous to contribution to improvement of dispersal diffusibility that an active material in an active material-containing fluid disperses and diffuses into an electrode in the downstream side of a fluid channel, i.e., in the side near a fluid outlet. SOLUTION: This fuel cell includes plural unit cells each having electrodes sandwiching an electrolyte film, and plural separators 3 disposed between the unit cells. The separator 3 has plural contact projecting parts 65 (75) facing to and contacting with the electrode with prescribed contact widths, and plural fluid channels 6a, 7a each having a channel width between the adjacent contact projecting parts 65 (75). The contact width of the contact projecting part 65 (75) on the side near a fluid outlet is set to a smaller value than the contact width of the contact projecting part 65 (75) on the side near a fluid inlet.

摘要： PURPOSE: To reduce electrical resistance and improve a sealing function by using a current collector made from a conductive rubber material, and bringing the current collecting section thereof into planar contact with an electrode plate elastically. CONSTITUTION: H2 and O2 gas inlets 12-1 and 13-1 are aligned with each of fuel feed and discharge ports 20 and 21, and a current collecting section 27 is placed within the center apertures 25 of each of supports 16 and 22. When separators 11 are stacked, an electrode substrate is laid in between with a current collector 17 kept in close contact with a positive electrode plate, and another current collector 19 with a negative electrode plate. Also, pairs so prepared are tightened with a set of pressure plates and made to adhere to each other. In this case, current collectors 17 and 19 made of conductive rubber are used and, therefore, the section 27 is kept in close contact with the electrode substrate under elastic deformation, thereby providing a complete planar contact state. According to this construction, contact resistance can be reduced and a cell function can be improved.
