Abstract
An electrochemical cell electrode plate structure, a high-pressure electrochemical cell device, and a method for preparing such devices, are provided. The inventive electrode plate structure comprises a laminar assembly of slotted plate-shaped components that provides more uniform openings or flow passages across the active areas thereof. The inventive high-pressure electrochemical cell device comprises at least one cell made up of both slotted and unslotted plate-shaped components that are free of material deformations typically resulting from the high compressive force employed during final cell assembly. The inventive method for preparing such devices basically involves preparing at least one laminated sub-assembly comprising unslotted component layers for the purpose of consolidating such weaker layers into stronger sub-assemblies prior to a final lamination step.
