摘要： A fuel gas flow field is formed on a surface of a rectangular first metal separator. The fuel gas flow field includes flow grooves extending in the direction of gravity. An outlet buffer is provided at a lower end of the fuel gas flow field. The outlet buffer includes an inclined surface inclined toward a fuel gas discharge passage. The fuel gas discharge passage is positioned below the outlet buffer. Outlet channel grooves are formed by ridges provided between the fuel gas discharge passage and the outlet buffer. Lower ends of the ridges are arranged in a zigzag pattern.

摘要： A first metal separator of one of adjacent power generation cells and a second metal separator of the other of the adjacent power generation cells are directly stacked together to form a coolant flow field. The first metal separator has a press line protruding toward the coolant flow field, between a fuel gas flow field and an inlet buffer. The second metal separator has a press line protruding toward the coolant flow field, between an oxygen-containing gas flow field and an inlet buffer. The press lines contact each other to limit flow of the coolant into a back surface buffer.

摘要： A power generation cell includes a membrane electrode assembly, with an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. Flow field walls are provided within the coolant flow field for preventing coolant from flowing into an area corresponding to an oxygen-containing gas inlet buffer, while allowing the coolant to flow into an area corresponding to an oxygen-containing gas outlet buffer. Likewise, flow field walls contact each other for preventing the coolant from flowing into an area corresponding to a fuel gas inlet buffer, while allowing the fuel gas to flow into an area corresponding to a fuel gas outlet buffer.
