Abstract
An electrolyzer is provided which includes at least one set of closely spaced electrode assemblies consisting of a flat anode and a flat cathode separated by a membrane permeable to ions. One side of the electrode assembly is supported by a rigid pressure plate while a flexible pressure plate disposed along the opposite side of the electrode assembly biased the anode and cathode towards each other. The flexible pressure plate includes a flat portion having contact pads struck and formed therefrom. The contact pads are sized to cover from 30 to 70% of the overall plate surface and include portions which are plane-parallel to the flat portion. The contact pads bent to one side are designed to be vertical on a longitudinal axis after mounting of the flexible pressure plate in an electrolyzer.
