摘要： A fuel battery includes unit cells, each of which includes a membrane electrode assembly having tow 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 pass 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 battery includes an oxidant gas flow passage having a downstream section, in which a gas diffusion porous body is arranged. The fuel battery includes a fuel gas flow passage having a downstream section, in which a gas diffusion porous body is arranged. A cooling medium flow passage is formed between a first separator of each unit cell of the fuel battery and a second separator of a unit cell adjacent to the unit cell. The flowing direction of a cooling medium in the cooling medium flow passage is the same as that of oxidant gas in the oxidant gas flow passage. An upstream section of the cooling medium flow passage is located closer to a surface of a membrane-electrode assembly that faces the oxidant gas flow passage adjacent to the cooling medium flow passage as compared with a downstream section of the cooling medium flow passage.

摘要： A gas passage forming body for a fuel battery includes gas passages and water guide passages. A communication passage is arranged between one of the water guide passages and a gas passage that is adjacent to the water guide passage and is in communication with the adjacent gas passage and water guide passage to permit water to move therethrough. An aid portion is arranged at water drainage ends of two adjacent ones of the water guide passages and aids bonding of water drained from the water drainage ends of the two adjacent ones of the water guide passages. Thus, water drainage from the water guide passages of the gas passage forming body is improved, and water in the gas passages is reduced. As a result, the battery performance of the fuel battery is improved due to an improvement in gas diffusion.

摘要： A gas channel forming member is located between a separator and a membrane electrode assembly. The gas channel forming member includes gas channels, which are arranged in parallel with each other on a surface that faces the membrane electrode assembly, water channels, which are formed on a surface that faces the separator, and inner communication passages. The water channels are each located between adjacent two of the gas channels. The inner communication passages communicate the gas channels and the water channels with each other. Each water channel is formed such that the flow cross-sectional area in an outlet section including an outlet opening is larger than the cross-sectional area of an upstream section, which is upstream of an adjacent to the outlet section in the flow direction of the oxidant gas.

摘要： A gas channel forming plate includes protrusions, which extend parallel with each other, gas channels that are respectively located between each adjacent pair of the protrusions, and water channels, which are respectively formed on the back surface of each protrusion. Each protrusion includes first communication portions and second communication portions. Each first communication portion includes a first opening. Each second communication portion includes a second opening. The second communication portions of each protrusion constitute an expanding region, in which the opening area of the second opening in each second communication portion is greater than the opening area of the first opening of each first communication portion, to limit introduction of water to the water channel on the back side of the protrusion using capillary action by the second communication portions.
