摘要： A fuel gas inlet is provided at an outer circumferential edge portion of a second separator. First fuel gas flow passage grooves for supplying a fuel gas to an anode electrode are formed on a side of a surface of the second separator. First fuel gas connecting flow passages, which make communication between the fuel gas inlet and the first fuel gas flow passage grooves, include flow passage lo grooves which are provided on a side of a surface, and through-holes which penetrate through the second separator to make communication with the first fuel gas flow passage grooves. Accordingly, excellent sealing performance is ensured with a simple structure, and it is possible to realize a thin-walled fuel cell.

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： An assembling operation of a fuel cell is effectively simplified. With the simple and economical structure, the desired sealing function is achieved. The fuel cell includes a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly. Connection channels are provided on the first metal separator. The connection channels connect the oxygen-containing gas supply passage and the oxygen-containing gas discharge passage to the oxygen-containing gas flow field. The membrane electrode assembly has first overlapping portions overlapped on the connection channels for sealing the connection channels. The first overlapping portions comprise, in effect, a gas diffusion layer.

摘要： Flow guides forming an inlet channel are formed on a surface of a metal separator of a fuel cell. The flow guides overlap a section of an outer seal provided on the other surface of the metal separator. When a load is applied to the flow guides and the overlapping section in a stacking direction of the fuel cell, the flow guides and the overlapping section are deformed substantially equally in the stacking direction to the same extent. The line pressure of the flow guides and the line pressure of the overlapping section are substantially the same. The seal length L1 of the flow guides and the seal length L2 of the overlapping section are substantially the same.

摘要： Disclosed is an electrode electrolyte for solid polymer fuel cells, which uses a polymer electrolyte containing a polyarylene copolymer containing a nitrogen-containing aromatic ring having a substituent represented by —SO3H, —(O(CH2)hSO3H or —O(CF2)hSO3H (wherein h represents an integer of 1-12). By having such a constitution, the electrode electrolyte for solid polymer fuel cells can be produced at a low cost, while being excellent in proton conductivity, dimensional stability, hydrothermal resistance and mechanical strength. In addition, this electrode electrolyte for solid polymer fuel cells enables to recover a catalyst metal.
