Abstract: 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.

Abstract: 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.

Abstract: A fuel cell includes power generation cells and an end cell. Each power generation cell has in it a gas passage, through which power generation gas passes. The fuel cell includes an introducing conduit, which distributes and introduces the power generation gas into the gas passages, and a discharging conduit, which merges flows of the power generation gas after passing through the gas passages and discharges the merged flow. The end cell has in it a bypass passage, which connects the introducing conduit and the discharging conduit to each other. The bypass passage is composed of parallel channels, each of which is independently connected to the introducing conduit. The parallel channels include lower parallel channels and upper parallel channels. The pressure loss in each of the lower parallel channels is smaller than the pressure loss in each of the upper parallel channels.

Abstract: A channel forming body used in a fuel cell module has a gas channel, a water conduit, and a communication path that provides communication between the gas channel and the water conduit. When a ridge is seen in a cross-section perpendicular to a channel extension direction, one of both ends of an external shape of the ridge is shaped so as to be located closer to a center of the ridge than an imaginary surface of the channel assumed to extend in a straight line along the channel extension direction. Portions of the ridge located closer to the center of the ridge are formed opposite from each other at left and right ends of the external shape of the ridge with the communication path interposed therebetween.

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.

Abstract: 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.
