    摘要： A unit cell has a membrane electrode assembly. The membrane electrode assembly includes a cathode, and an anode, and a solid polymer electrolyte fuel cell interposed between the cathode and the anode. The membrane electrode assembly is interposed between a first separator and a second separator. A thin cooling plate is interposed between the second separator and another first separator. A first coolant flow passage and a second coolant flow passage are formed on both surfaces of the cooling plate. The coolant flows along one surface of the cooling plate, and turns back at an end of the cooling plate to flow along the other surface of the cooling plate.

    摘要： A fuel cell stack (10) includes a first sub-stack (12), a second sub-stack (14), and a third sub-stack (16) disposed in the flow direction of an oxidizing gas. An intermediate plate (18a) is interposed between the first and second sub-stacks (12, 14), and an intermediate plate (18b) is interposed between the second and third sub-stacks (14, 16). In this fuel stack (10), the flow of an oxidizing gas is set such that the oxidizing gas flows in series in the direction from the first sub-stack (12) to the third sub-stack (16). Between the sub-stacks additional oxidizing gas supplies (70,74) are provided through which oxidizing gas of lower humidity than the humidity of the oxidizing gas entering the first sub-stack is supplied. This arrangement allows an efficient management of the humidity water content of the oxidizing gas with sufficient moisturizing of the solid polymer membrane whilst avoiding excessive condensation of water vapour within the stack.

    摘要： A fuel gas passage, an oxygen-containing gas passage, and a coolant passage extend through a fuel cell stack. Each of the fuel gas passage and the oxygen-containing gas passage is formed by serially connecting passages between the first through third fuel cell modules. The fuel gas flows through the fuel gas passage, and the oxygen-containing gas flows through the oxygen-containing gas passage from the first fuel cell module toward the third fuel cell module. The coolant passage is formed by serially connecting passages between the first through third fuel modules. The coolant flows through the coolant passage from the third fuel cell module toward the first fuel cell module. The direction of the flow of the coolant is opposite to the direction of the flows of the fuel gas and the oxygen-containing gas.

    摘要： Disclosed is a fuel cell stack comprising fuel cell units and first and second separators which are alternately stacked with each other. Wedge members are integrally inserted, over the plurality of fuel cell units, into communication holes of a fuel gas supply passage, an oxygen-containing gas supply passage, and a cooling water supply passage, as well as a fuel gas discharge passage, an oxygen-containing gas discharge passage, and a cooling water discharge passage. A fluid is uniformly delivered to each of the fuel cell units by the aid of the wedge members. Accordingly, the fluid of any one of a fuel gas, an oxygen-containing gas, and a cooling medium is uniformly delivered to each of the fuel cell units. Further, it is possible to simplify the arrangement of the fuel cell stack.
