Abstract
Material is incorporated in each of the cell separator membranes of an electrochemical cell having a layered construction wherein a plurality of commonly connected metal anode layers and a plurality of commonly connected cathode layers are arranged in a closely packed, stacked sandwich construction, separated by a plurality of thin insulating separator membranes which gives each cell separator a known resistance value which can be measured thereby allowing total cell resistance to be readily tested.
