摘要： There is provided a terminal plate comprising a plate stacked body including a first metal plate that is electrically conductive and has a current collecting terminal for power collection, and second metal plates that have higher corrosion resistance than the first metal plate and are placed across the first metal plate. A first gasket is mounted to the second metal plate and is provided to surround at least a gas flow hole used for supply of a gas on the second metal plate-side. A second gasket is mounted to the second metal plate and is provided to surround a cooling water flow area which communicates with a cooling water flow hole used for supply of cooling water on the second metal plate-side. The current collecting terminal is protruded from a plate outer circumferential end of the first metal plate in a direction from one flow hole of the gas flow hole and the cooling water flow hole toward the plate outer circumferential end of the first metal plate. This configuration enables the current collecting terminal to be cooled down from the second metal plate-side via the first metal plate.

摘要： A fuel cell separator includes a separator main body having a first surface and a second surface, and a first seal member disposed on the first surface. When a region on the first surface of the separator main body corresponding to an electrode member disposed on the second surface is defined as a power generation region, and a region on the first surface of the separator main body corresponding to an in-cell seal member is defined as a seal region, a displacement/vibration reducing member made of polymer is disposed at a part of the seal region. The displacement/vibration reducing member includes multiple protrusions and a coupling portion. When viewed in plan view, an axis line connecting the centers of the figures of the adjacent protrusions does not coincide with a center line passing through the widthwise center of the coupling portion. The coupling portion has a gate cut mark.

摘要： A separator for a fuel cell, to be disposed opposing to a membrane electrode assembly, is provided. The separator includes a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power, an outer edge portion located in an outer edge of the separator central area portion, a rubber molded body made of rubber, the rubber molded body being formed in the outer edge portion by die-casting a die-casting rubber material using die, and an adhesive layer formed in the outer edge portion, for adhering the rubber molded body to the outer edge portion. The adhesive layer is formed over an adhesive layer area that includes and is larger than an area where the rubber molded body is die-casted in the outer edge portion. Thus, a disadvantage due to burrs which are generated when die-casting the rubber molded body can be reduced.

摘要： A fuel cell system for a load device may include a fuel cell, a battery, and a controller configured to control the fuel cell and the battery. The controller may be configured to: cumulatively calculate first accumulated electric energy generated by the fuel cell; cumulatively calculate a power generation efficiency average at the time of storage of the first accumulated electric energy; calculate required power generation efficiency to generate electric power that meets a power demand of the load device; under a first condition where the power generation efficiency average is lower than the required power generation efficiency, cause the fuel cell to generate electric power that meets the power demand; and under a second condition where the power generation efficiency average is higher, cause the fuel cell to generate electric power at a specific operating point and cause the battery to discharge deficient electric power.
