摘要： A manufacturing method for manufacturing a fuel cell includes a laser application step and a bonding step. In the laser application step, a laser beam is applied to a carbon film of a separator including a metal plate and the carbon film covering a surface of the metal plate such that the metal plate is exposed by removing the carbon film within an application range of the laser beam. In the bonding step, the separator is bonded to a resin member within a range including at least part of a range where the metal plate is exposed.

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 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.

摘要： Stacked unit cells 100 of a fuel cell each comprise a membrane electrode assembly 10, a pair of gas separators 40 and 50, and a first sealing portion 26 provided between the pair of gas separators. The fuel cell further comprises a second sealing potion provided between adjacent ones of the unit cells, a first manifold in which reaction gas flows, and a second manifold in which a coolant flows. One of the first sealing portion and the second sealing portion is an adhesive sealing portion, and another one of the first sealing portion and the second sealing portion is formed of a gasket. The adhesive sealing portion and the gasket are provided along the outer circumference of the manifold, in the fuel cell as viewed in a stacking direction. The gasket and the adhesive sealing portion are arranged in this order from a side closer to the manifold.

摘要： An object is to improve the durability of a seal member such as a gasket. A bottom 23 is a seal surface that comes into contact with a gasket 40 placed between the bottom 23 and an adjacent cell. A cooling water manifold 411 is a flow path for cooling water that is formed to pass through a separator for fuel cell in its thickness direction. A flange 24 is protruded from one surface of a first separator in the thickness direction to surround part of the cooling water manifold 411. An area between respective ends T1 and T2 of the flange 24 is an opening K that forms a flow path in an in-plane direction of the first separator. An inclined surface 22 located on a limit line RL of the flange 24 is formed to face the gasket 40, in order to limit the move of the gasket 40 in an adjacent cell. At the end T1 located on the limit line RL, a surface opposed to the gasket 40 is covered by a protective film 70 for protecting the gasket.

摘要： A single cell includes a linear sealing portion bonded to a pair of gas separators, the sealing portion being provided between the gas separators. A fuel cell in which a plurality of single cells is laminated includes: a gasket provided between the single cells adjacent to each other; a first manifold communicating with an inside-cell gas passage; and a second manifold communicating with an inter-cell refrigerant passage. The gasket includes a first gasket placed to surround the outer periphery of the first manifold and configured to seal the first manifold, and a second gasket configured to seal the second manifold and an inter-cell refrigerant passage. When the fuel cell is viewed from the laminating direction, the first gasket, the sealing portion, and the second gasket are placed in this order from the first manifold toward the second manifold between the first manifold and the second manifold.
