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 fuel cell stack having stacked unit fuel cells, each having a pair of separators between which a membrane electrode assembly is provided, which includes an anode and a cathode. Each separator has protruding lines arranged vertically in a zigzag manner, which protrude in a direction going away from the membrane electrode assembly. A space between the anode and the protruding lines of the separator facing the anode is used as a fuel gas passage. A space between the cathode and the protruding lines of the separator facing the cathode is used as an oxidant gas passage. At least part of the separators are each arranged in close contact with another separator so that a coolant passage through which a coolant flows horizontally is formed between both separators. A lower area of the coolant passage has a larger flow resistance than that of an upper area thereof.

摘要： A fuel cell stack includes stacked unit fuel cells provided between end holding members, each unit fuel cell having a membrane electrode assembly including an anode and a cathode. A pair of separators respectively contact the anode and the cathode, and respectively form reaction gas passages between one separator and the anode, and between the other separator and the cathode. For each reaction gas passage, a gas supply passage and a gas discharge passage are formed through the unit fuel cells and one end holding member so that they communicate with the reaction gas passage of each unit fuel cell, and a drainage passage is also formed through the unit fuel cells and one end holding member. An end of the drainage passage and an end of the gas discharge passage on the side of the other end holding member are joined to each other.
