摘要： A fuel cell includes a cell structure, an oxidizing agent flow path, a fuel flow path, and an anode-side current collector. The cell structure includes a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode. The oxidizing agent flow path is formed adjacent to the cathode and away from the solid electrolyte layer. The oxidizing agent flow path is a flow path for supplying a gas that contains an oxidizing agent to the cathode. The fuel flow path is formed adjacent to the anode and away from the solid electrolyte layer. The fuel flow path is a flow path for supplying a fuel gas that contains water vapor and a hydrocarbon to the anode. The anode-side current collector is disposed adjacent to the anode and away from the solid electrolyte layer. The anode-side current collector is in contact with the anode.

摘要： A separator-integrated gasket is provided for making an electrolyte membrane unlikely to be deformed when a stack is assembled. The separator-integrated gasket for a fuel battery includes a lip-shaped gasket, first and second separator components, and a flat-shaped gasket. The first and second separator components are made of press-workable metal plates, and include first and second three-dimensional shape portions, respectively. The first separator component includes a surface that is on a side opposite to a protruding direction of the first three-dimensional shape portion and on which a gasket attachment groove holding the lip-shaped gasket is formed. The second separator component includes a surface that is on a side opposite to a protruding direction of the second three-dimensional shape portion and on which a three-dimensional shape fitting groove accommodating the first three-dimensional shape portion is formed. The flat-shaped gasket is held on an outer surface side at the second three-dimensional shape portion. The first and second three-dimensional shape portions protrude in the same direction while mutually adjusted in positions on a flat surface. The first and second separator components are joined to each other while superposed over each other in a thickness direction.

摘要： At least one embodiment relates to a method for transforming at least part of a valve metal layer into a template that includes a plurality of spaced channels aligned longitudinally along a first direction. The method includes a first anodization step that includes anodizing the valve metal layer in a thickness direction to form a porous layer that includes a plurality of channels. Each channel has channel walls and a channel bottom. The channel bottom is coated with a first insulating metal oxide barrier layer as a result of the first anodization step. The method also includes a protective treatment. Further, the method includes a second anodization step after the protective treatment. The second anodization step substantially removes the first insulating metal oxide barrier layer, induces anodization, and creates a second insulating metal oxide barrier layer. In addition, the method includes an etching step.

摘要： A fuel cell stack includes a cell stack in which a plurality of unit cells each including a pair of separators is stacked together. The fuel cell stack includes a seal sheet configured to seal between adjacent unit cells. The pair of separators each include a seal line rib on a seal sheet side of the separator, the seal line rib serving as a seal line with the seal sheet. Among two facing separators that are a first facing separator and a second facing separator facing each other while sandwiching the seal sheet between the adjacent unit cells, the first facing separator includes a protruding portion on at least one part of the seal line rib, and the second facing separator includes a recessed portion in the seal line rib that is configured to fit the protruding portion.
