Abstract: The present separator is used in a stack structure in which a cell and the separator are stacked alternately. The cell has a base layer including an electrolyte membrane. The separator includes a metal plate and a ring-like seal member. The seal member is arranged on a surface of the metal plate. The metal plate includes a regulator. The regulator is provided near the seal member and contacts the base layer. As a result, it becomes possible to reduce a likelihood that the seal member will be compressed excessively in a stacking direction in the stack structure.

Abstract: The present water electrolyzer has a stack structure with a cell and a separator stacked alternately. The separator includes a metal plate and a flow path member. The metal plate has a distribution hole. The flow path member is located between a base layer of the cell and the metal plate in a stacking direction. The flow path member surrounds the distribution hole in a ring-like shape when viewed in the stacking direction. The flow path member includes a flow path through which a gas diffusion layer of the cell and the distribution hole communicate with each other. As a result, it becomes possible to cause gas or water to flow between the gas diffusion layer and the distribution hole through the flow path formed at the flow path member. This achieves reduction in the number of the metal plates to be used as the separator.

Abstract: A bed includes a bed body, ascending and descending means, and an auxiliary leg member. The bed body has a floor frame, and a main leg member fixed to the floor frame. The ascending and descending means has an ascending and descending link, and an extensible and retractable actuator for operating the ascending and descending link. The ascending and descending link holds the bed body with one of the opposite ends, and it holds the auxiliary leg member with the other one of the opposite ends. For instance, the ascending and descending link constitutes a parallel link, the floor frame constitutes one of the parallel elements of the parallel link, and the auxiliary leg member constitutes the other one of the parallel elements of the parallel link, thereby enabling the whole bed body including a mattress to ascend and descend.
