    摘要: A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first and second metal plates. The coolant flow field is connected to inlet buffers and outlet buffers. Protrusions for limiting the flow of a coolant are provided at the inlet buffers and the outlet buffers on upper and lower opposite end positions of the coolant flow field.

    摘要: A separator comprises a first and second metal plates laid over each other. A cooling medium flow passage is integrally provided between the first and second metal plates. The cooling medium flow passage has inlet buffer portions communicating with a cooling medium inlet communication hole, outlet buffer portions communicating with a cooling medium outlet communication hole, and linear flow passage grooves linearly extending in the direction of arrow B and that of arrow C.

    摘要: A coolant supply passage, a coolant discharge passage, and an air-releasing passage extend through first and second metal plates of a metal separator in a stacking direction of the first and second metal plates. The coolant supply passage and the coolant discharge passage are provided at vertically middle positions of opposite horizontal ends of the separator. A coolant flow field is connected between the coolant supply passage and the coolant discharge passage. The air-releasing passage for releasing air from the coolant flow field is formed above the coolant discharge passage. At least part of the air-releasing passage is positioned above the top of the coolant flow field.

    摘要: A fuel cell stack includes a stacked body, a negative and positive terminal plates stacked on opposite ends of the stacked body, insulators disposed outside the terminal plates, and the end plates disposed outside the end plates. The insulator includes a first insulator plate, a second insulator plate, and a third insulator plate. Bypass passages are formed on the first insulator plate and the third insulator plate for discharging water in an oxygen-containing gas and water in a fuel gas.

    摘要: A fuel cell includes a membrane electrode assembly and separators sandwiching the membrane electrode assembly. Each of the separators includes first and second metal plates. When the fist and second metal plates are stacked together, an inlet buffer and an outlet buffer are overlapped with each other in the stacking direction. A plurality of bosses in the inlet buffer and a plurality of bosses in the outlet buffer are not overlapped with each other.
