Abstract
A gasket device includes: a first gasket made of an elastic body; and a separator having a pair of surfaces facing away from each other. The first gasket is in an annular shape and attached to the surface of the separator in such a manner as to surround an opening. Moreover, the first gasket includes an annularly extending lip projecting in a direction that the surface of the separator faces. The lip has different heights on a side of the opening and an opposite side to the side of the opening.

A gasket for sealing a space between opposed members in a water electrolysis device or a fuel battery, the gasket being made of an elastic body, the gasket being in an annular shape, the gasket being configured to be fixed to one of a pair of surfaces of a separator in such a manner as to surround the space, the pair of surfaces facing away from each other, the gasket comprising:
- an annularly extending lip;
- an inner surface that is an annular surface connected to the lip on a side of the space;
- an outer surface that is an annular surface connected to the lip on an opposite side to the space;
- an inner end surface that is an annular surface facing an inner side;
- and
- an outer end surface that is an annular surface facing an outer side, wherein
- the lip is configured to project in a direction that the one of the pair of surfaces of the separator faces, and
- a height of the lip on the side of the space is higher than a height of the lip on the opposite side to the space,
- the inner surface is connected to the inner end surface, and
- the outer surface is connected to the outer end surface.
