摘要： A fuel cell includes a cell unit. The cell unit includes a first separator, a second separator, and an electrolyte-electrode assembly. The electrolyte-electrode assembly is sandwiched between the first separator and the second separator in a stacking direction. The outer periphery of the electrolyte-electrode assembly is integrally provided with frame members composed of a polymer material. Fluid communication holes are provided as through holes in the stacking direction in each of the frame members. The seal member is sandwiched between the frame members that are adjacent to each other in the stacking direction. The first and second separators each have two plates with an identical outer shape. Each of the frame members has a rib projecting in a thickness direction of the frame member, at least around one of an outermost periphery of the frame member and the fluid communication holes.

摘要： A fuel cell system includes an oxidant gas supply apparatus and a fuel gas supplier. The oxidant gas supply apparatus includes first and second open/close valves disposed respectively in oxidant gas supply and discharge lines, and an oxidant gas flow field having a first volume and formed between the first and second open/close valves. The fuel gas supplier includes third and fourth open/close valves disposed respectively in fuel gas supply and discharge lines, and a fuel gas flow field having a second volume and formed between the third and fourth open/close valves. A ratio of the first volume to the second volume is determined such that substantially all oxygen in the oxidant gas remaining in the oxidant gas flow field is consumed by reaction with the fuel gas remaining in the fuel gas flow field when the oxidant gas flow field and the fuel gas flow field are closed.

An inlet buffer is connected to the inlet of the fuel gas flow field, and an outlet buffer is connected to an outlet of the fuel gas flow field. The inlet buffer is deeper than the outlet buffer. Therefore, the pressure loss in the inlet buffer is smaller than the pressure loss in the outlet buffer.
