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: 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.
