摘要： A fuel cell stack includes stacked cells, each including a sheet-shaped power generation portion, two separators, a gas passage defining plate that includes a gas passage portion through which reactant gas flows, and a frame member that includes a supply port and a discharge port. The gas passage portion includes opposing portions extended in a flow direction of the reactant gas and arranged in parallel in an orthogonal direction. A main passage is defined between each opposing portion and the power generation portion. The gas passage portion includes a first passage portion adjacent to the supply port in the flow direction and a second passage portion adjacent to the first passage portion in the orthogonal direction. The main passages of the second passage portion each have a larger cross-sectional flow area than the main passages of the first passage portion.

摘要： A fuel cell stack includes stacked cells, each including a sheet-shaped power generation portion, two separators, a gas passage defining plate that includes a gas passage portion through which reactant gas flows, and a frame member that includes a supply port and a discharge port. The gas passage portion includes opposing portions extended in a flow direction of the reactant gas and arranged in parallel in an orthogonal direction and wavy portions each having a wavy cross-sectional shape orthogonal to the orthogonal direction. The gas passage portion includes a first passage portion adjacent to the supply port in the flow direction and a second passage portion adjacent to the first passage portion in the orthogonal direction. The connection passages of the second passage portion each have a larger cross-sectional flow area than the connection passages of the first passage portion.

摘要： A separator for a fuel cell includes protrusions and gas passage portions. The protrusions each include a contact surface configured to contact a power generation portion. The gas passage portions are each arranged between two adjacent ones of the protrusions. An upstream side and a downstream side are defined with reference to a direction in which reactant gas flows through the gas passage portions. The protrusions each include a downstream end. The contact surfaces of the protrusions each include a first groove extending along an extending direction of the protrusions. The downstream end of each of the protrusions includes a separation surface. The separation surface is continuous with the contact surface on the downstream side and separated from the power generation portion. The separation surface includes a second groove that is continuous with the first groove.

摘要： In a first step, a molding die is immersed in a raw liquid including cellulosic fibers. Then, the liquid of a raw liquid is sucked through a net material by a liquid suction part, so as to cause the cellulosic fibers to be laminated on the net material. In the second step, the cellulosic fibers laminated on the net material are dried, so as to form a protrusion. In the third step, the dried protrusion and the communication part are removed from the molding die. A passage part of the communication part is formed at a position where a projection portion had been arranged, the passage part being configured to communicate an inside of the protrusion with an outside of the protrusion.

摘要： A step device for a vehicle includes: a movable step supported under a door opening; a coupling member that, in a state of being supported by a sliding door, engages with the movable step to move the movable step in a vehicle width direction in conjunction with opening and closing of the sliding door; a support arm that has a first pivot-joint point relative to a vehicle body and a second pivot-joint point relative to the movable step, and supports the movable step toward an upper side; and a pressure bearing member that is provided at a position between the first pivot-joint point and the second pivot-joint point and bears the load of the support arm by coming into sliding contact with the support arm.

摘要： 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.

摘要： 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.
