摘要： A coolant flow field of a fuel cell stack includes a power-generation-portion-cooling flow path including a portion overlapping a power generation section of a membrane electrode assembly, a bypass flow path provided on outer peripheries of separators, a main supply flow path extending from a coolant supply passage through the bypass flow path and communicating with the power-generation-portion-cooling flow path, and a bubble release flow path extending from an upper portion of the coolant supply passage in the gravity direction toward the bypass flow path and communicating with the bypass flow path, wherein the bubble release flow path extends upward in the gravity direction above the coolant supply passage.

摘要： A reactant gas channel part provided outside an auxiliary machinery case of a fuel cell system is connected to a case through hole. A plurality of channel seal members are provided between the auxiliary machinery case and the reactant gas channel part, where the channel seal members are arranged side by side in the radial direction of the case through hole and surround the case through hole. The reactant gas channel part has an opposing surface that faces a surrounding portion of the auxiliary machinery case that surrounds the case through hole. The channel seal members include an inner seal member abutting on the opposing surface and an outer seal member disposed radially outside of it. A connection channel communicating with an internal space of the auxiliary machinery case is formed between the inner seal member and the outer seal member.

摘要： An air intake structure for a fuel cell vehicle includes an air inlet port, an air passage, and a water separation passage. The air inlet port is provided in a front space of the fuel cell vehicle in which a fuel cell is accommodated. The air passage is connected to the air inlet port such that air flows from the air inlet port to the fuel cell through the air passage. The air passage has a branch point and a first minimum passage sectional area located downstream with respect to the branch point. The water separation passage has a downstream opening in the front space and extending from the branch point to the downstream opening below the air passage to separate water from the air. The water separation passage has a second minimum passage sectional area which is smaller than the first minimum passage sectional area.
