A gasket having the form of a frame is provided with a curved portion at an inner or outer periphery thereof. When used in combination with a similarly configured gasket, the two gaskets may together, upon compression, form a pinch seal. The curved portion may be provided with a chemically resistant material.

Gasket with curved configuration at peripheral edge

An electrode structure for use, for example, in a bipolar electrolyser comprising (i) a pan with a dished recess and a flange around the periphery thereof for supporting gasket means for sealing a separator between the flanges in adjacent electrode structures, which separator is disposed between the surface of the anode of a first electrode structure and the cathode of a second electrode structure such that the anode surface is substantially parallel to and faces but is insulated and spaced apart from the cathode surface by the separator and is hermetically-sealed to the separator, (ii) an electrically conductive plate spaced from the pan, (iii) a plurality of electrically-conductive members to which the electrically conductive plate is electroconductively attached and which provide electrically-conductive pathways between the pan and the electrically conductive plate, (iv) inlet for electrolyte and (v) outlets for liquids and gases wherein where the electrode structure is an anode structure the dished recess is provided with a plurality of inwardly projecting projections and where the electrode structure is a cathode structure the dished recess is provided with a plurality of outwardly projecting projections such that the inwardly projecting projections in the dished recess of the pan of the anode structure mate with the outwardly projecting projections in the dished recess of the pan of an adjacent cathode structure in a bipolar electrolyser comprising a plurality of the electrode structures.
