NOVELTY - A cell has a separator with an anode surface (18) of anodes (20) and cathode surface (22) of cathodes (24) and exposed to their corresponding compartments. The electrodes with electrically conductive catalyst particles are separated by an ion exchange polymer (26). The electrodes are connected with each other to form a cells. A feed region (32) connects the electrodes of adjacent cells.    USE - For fuel cells in production of electrical energy.    ADVANTAGE - The ion exchange polymer electrolyte is less complicated, lighter and easier for transportation. The anodes and cathodes has good gas permeability. The collector screen and the ion exchanger resin, are partially embedded to enhance permeability of gases. The electricity cost is reduced when electrochemical cell is used.    DETAILED DESCRIPTION - An electrochemical cell (10) has an anode (12), cathode compartment (14) separated by a separator (16).The separator contains several current collector screen (30). A feed through region connects the anode and cathode of adjacent cells.    An INDEPENDENT CLAIM is also included for the process of making a separator in which conductive screens, sheets of thermoplastic ion exchange precursor are overlapped such that sheets are positioned between adjacent screens. The laminate is pressed by heating to a sufficient temperature such that the polymers are softened and the screens get attached to form unitary structure with first and second surfaces. The screen at the overlapped portion is separated by ion exchange polymer precursor. Subsequently ion exchange polymer is hydrolyzed and several electrodes with electrically conductive catalyst particle are arranged side by side on the first and second unitary structure of overlapped portion. The electrodes on the first side is connected to the second side to form counter electrode pairs.
