摘要： A fuel cell includes a plurality of laminated gas chambers, a plurality of separators that separate the gas chambers, intake passages for supplying fuel gas and oxidizing gas, exhaust passages for emitting the fuel gas and the oxidizing gas, intake ports to supply fuel gas and oxidizing gas from the intake passages to the gas chambers, exit ports to exit the fuel gas and the oxidizing gas from the gas chambers to the exhaust passages, and rectifying plates located at one end of the intake ports and extending across at least one of the gas intake passages. Each of the rectifying plates effectively restricts direct gas flow from one of the intake passages to the intake ports. Therefore, the number of gas chambers can be increased as compared to conventional fuel cells. Even though the number of gas chambers is increased, each gas chamber uniformly receives gas due to the excellent gas distribution achieved by the rectifying plates.

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.
