Abstract
Bonded, coherent fibrous web substrates well adopted as cathodic elements for electrolytic cells and advantageously incorporating an electrocatalytic agent, include a web matrix which comprises a plurality of fibers, at least a portion of which comprising electrically conductive fibers, e.g., carbon fibers, said plurality of fibers being coherently bonded together with a fluorine-containing polymer, and said web substrate having a resistivity of up to about [0.4] 4.0 .OMEGA..cm.
Claims41
A bonded, coherent fibrous web substrate including a fibrous web matrix which comprises a plurality of fibers, at least a portion of which comprising electrically conductive fibers, and a binder consisting of a fluorine-containing polymer, said plurality of fibers being coherently bonded together with said fluorine-containing polymer, and said web substrate having a resistivity of up to about [0.4 .OMEGA. cm.] 4.0 .OMEGA..cm.
A bonded, coherent fibrous web substrate including a fibrous web matrix which comprises a plurality of fibers, at least a portion of which comprise electrically conductive fibers, and a binder consisting of a fluorine-containing polymer, said plurality of fibers being coherently bonded together with said fluorine-containing polymer, and said web substrate having a resistivity of up to about [0.4 .OMEGA. cm] 4.0 .OMEGA..cm , wherein said web matrix comprises electrically non-conductive fibers having a resistivity in excess of 0.4 .OMEGA. cm, the diameters of which being less than about 1 mm and the lengths of which being in excess of about 0.5 mm and electrically conductive fibers.
