METHOD OF MANUFACTURING OF FUEL ELEMENT WITH SOLID POLYMER ELECTROLYTE Russian patent published in 2008 - IPC H01M8/10 

FIELD: electrical engineering; fuel elements.

SUBSTANCE: anodic (11) and cathodic (12) electrode layers ate mounted on grid substrate, electrode layers within integrated metal structure include porous electrode carriers (3) and (3′), solid shunts (4) and (4') of porous electrode carriers (3) and (3′) and leads (5) and (5′) to drain current from electrode layer. For that purpose odd areas designed for electrode carriers (3) and (3′) are protected on grid substrate with thermoplastic film (2). Grid substrate surface uncovered with film is copper and nickel plated to produce solid shunts (4) and (4′), leads (5) and (5′). Back surface of electrode layers (11) and (12) is rough copper deposit plated and then nickel plated that is corrosion-resistant for solid polymer electrolyte contact. One surface of solid polymer electrolyte (9) has catalytic coating (10). Adhesive padding (8) is formed on the surface of shunts (4) and lead (5) of electrode layer (11). Gaps correlating to adhesive padding (8) are cut in film covering solid polymer electrolyte (9). Surfaces of electrode (12) carriers (3′) has catalytic coating (6) consisting of fine-dispersed metallic catalyst and fluorocarbon polymer. Layers (11), (9), (12) are integrated and exposed to thermal pressing. Rough surface of electrode layers at that penetrates the film of solid polymer electrolyte, and corresponding shunts and leads of electrode layers (11) and (12) are glued over (7). It results in fuel element (fig. 5), supplied with minor fuel elements (13) in number equal to electrode carriers (3) of electrode layer (12) and respectively to (3') of electrode layer (11).

EFFECT: high performance and reliability of fuel element, as well as reduction of specific quantity of metal and productivity improvement of integrated layer-built structure of fuel element.
