Separator-spacer for electrochemical systems
First Claim
1. An integral separator and spacer for use in an electrochemical cell having circulating electrolyte flowing therethrough, wherein said separator-spacer is a sheet disposed between adjacent electrodes of said cell and comprises a frame disposed about a microporous web, said web being thinner than said frame in order to form internal compartments between said separator-spacer sheet and said adjacent electrodes, so that circulating electrolyte can flow about said electrodes, said web providing ionic communication between adjacent compartments of said cell, a surface on each side of said web covered with projections for maintaining a spaced compartmental distance between said separator-spacer and said adjacent electrodes.
