    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: An oxygen-containing gas flow field for supplying an oxygen-containing gas from an oxygen-containing gas supply passage to an oxygen-containing gas discharge passage is formed on a first metal plate. The oxygen-containing gas flow field includes oxygen-containing gas flow grooves as serpentine flow grooves having two turn regions T1, T2. The oxygen-containing gas flow grooves have substantially the same length. The oxygen-containing gas flow grooves are connected to an inlet buffer and an outlet buffer at opposite ends. The inlet buffer and the outlet buffer have a substantially triangular shape, and are substantially symmetrical with each other.

    摘要: A fuel cell includes a membrane electrode assembly and first and second metal plates sandwiching the membrane electrode assembly. The first metal plate has positioning ribs for positioning the outer region of the membrane electrode assembly. The first and second metal plates are positioned in alignment with each other by the first and second insulating bushings attached to first and second positioning holes of the first and second metal plates. Further, the first and second metal plates sandwiching the membrane electrode assembly are fastened together by a plurality of metal clip members.
