摘要： Each of collectors 22 of an electrode structure 20, which partially constitutes a polymer electrolyte fuel cell, is formed from a metal lath MR having a large number of through-holes. A stopping portion 22a in which the through-holes are reduced in diameter is formed at a peripheral end portion of the collector 22. The peripheral end portion of the collector 22 is folded; subsequently, the folded peripheral end portion is pressed, thereby forming the stopping portion 22a. A resin seal portion 23 for sealing introduced fuel gas and oxidizer gas is formed integrally with the stopping portions 22a by insert molding which is performed such that an injected molten resin encloses the stopping portions 22a. The resin seal portion 23 formed integrally with the stopping portions 22a can reliably prevent inflow of the molten resin toward central portions of the collectors 22.

摘要： A gas channel forming plate is arranged between a membrane electrode assembly and a flat separator base. The gas channel forming plate includes gas channels arranged on a surface that faces the membrane electrode assembly, water channels each formed on the back side of the protrusion between an adjacent pair of the gas channels, communication passages that connect the gas channels and the water channels to each other, and guide portions formed by causing an inner wall surface of a gas channel to protrude inward in the gas channel. The guide portions are formed such that the upstream edge of each communication passage is arranged in a range in which, in the velocity vector of the gas flowing in the gas channel, the directional component directed from the side corresponding to the membrane electrode assembly toward the flat separator base has a positive value.

摘要： A fuel battery includes unit cells, each of which includes a membrane electrode assembly having two gas diffusion layers. Gas passage forming bodies are stacked on an outer surface of each of the gas diffusion layers of each of the unit cells so that each of the unit cells includes a fuel gas passage and an oxidant gas passage. Each of the gas passage forming bodies includes water guide passages, each of which is located between adjacent ones of the gas passages. A communication passage is arranged between each of the gas passages and an adjacent one of the water guide passages to guide water from the gas passage to the water guide passage. The communication passage has a higher pressure loss than that of the gas passage.

摘要： A fuel cell includes a first separator and a second separator. A second protrusion is formed on a first sealing portion of the first separator. A concave portion is formed in a second sealing portion of the second separator. When fuel cells are stacked together sequentially in the vertical direction without displacing relative to one another, the center of the second protrusion and the center of the concave portion are aligned with each other. Even if the fuel cells are displaced while being stacked together, the upper fuel cell in the vertical direction is moved to decrease the distance between the center of the second protrusion and the center of the corresponding concave portion.

摘要： An electrode structure 15 is accommodated in a joint portion of frames 13 and 14. A first gas diffusion layer 19 and a first gas passage forming member 21 are laid on a first surface of the electrode structure 15, and a second gas diffusion layer 20 and a second gas passage forming member 22 are laid on a second surface of the electrode structure 15. A separator 23 is joined to surfaces of the frame 13 and the gas passage forming member 21, and a separator 24 is joined to surfaces of the frame 14 and the gas passage forming member 22. A porous layer 26 having continuous pores is located between the gas passage forming member 22 and the separator 24. A drainage promoting member 30 formed of a porous material having continuous pores is provided to communicate with a downstream end of a second gas passage T2 of the second gas passage forming member 22 and to communicate with a downstream end of the continuous pores of the porous layer 26. Generated water that has been drawn into the porous layer 26 from the second gas passage T2 by capillary action flows downstream by surface tension of water, and is then drawn into the drainage promoting member 30. The water drawn in by the drainage promoting member 30 is discharged into a discharging passage by fluid pressure of oxidation off-gas that flows from the second gas passage T2 into the continuous pores of the drainage promoting member 30. Accordingly, a fuel battery is provided in which generated water is prevented from remaining in the second gas passage T2 of the cathode side second gas passage forming member 22, and it is possible to prevent the power generation performance from being lowered by insufficient supply of oxidation gas to the electrode structure 15.
