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.

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.
Abstract translation: 用于燃料电池的气体通道形成体包括气体通道和导水通道。 连通通道设置在一个导水通道和与导水通道相邻的气体通道之间，并且与相邻的气体通道和导水通道连通，以允许水通过其移动。 辅助部分布置在两个相邻的导水通道的排水端，并且辅助从两个相邻的导水通道的排水端排出的水的接合。 因此，来自气体通道形成体的导水通道的排水得到改善，并且气体通道中的水减少。 结果，由于气体扩散的改善，燃料电池的电池性能得到改善。

Abstract: A fuel cell stack includes multiple power generating units and a dummy unit, and respectively providing openings providing reactant-gas supply manifolds. Each power generating unit includes one or more first supply passages extending from the opening to a central region thereof. The dummy unit includes one or more second supply passages extending from the opening to a central region thereof, and a second supply passage port at the highest position in the vertical direction among the second supply passage ports where the second supply passages are connected to the opening is located at a lower position in the vertical direction than a first supply passage port at the highest position in the vertical direction among the first supply passage ports where the first supply passages are connected to the opening.

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 fuel cell stack includes: a plurality of power generation cells stacked on top of each other; a dummy cell provided on at least one of both ends of the plurality of power generation cells, the dummy cell being configured not to generate electric power; and a reaction gas supply manifold extending through the plurality of power generation cells and the dummy cell. The dummy cell includes one or more dummy cell reaction gas introduction channels as a reaction gas introduction channel that introduces reaction gas from the reaction gas supply manifold to a center area of the dummy cell. At least one of the dummy cell reaction gas introduction channels is provided so as to connect to a bottom face at a lower side of the reaction gas supply manifold in a direction of gravitational force.
