Patent ID: 7014944

Claim:
A fuel cell electrode comprising: a non-woven network of conductive fibers, electroactive carbon material carrying one or more catalysts, and at least one polymeric substance selected from the group consisting of a binder and a repellancy agent to establish liquid-solid-liquid zone interface or gas-liquid-solid phase interface, whereby structure of the electrode is formed upon embedding electroactive carbon material into the network of conductive fibers by a deposition process selected from the group consisting of coating, blading and spraying, and whereby specific catalyst density of the electrode is within the range of 0.8 mg/cm 3 to 50 mg/cm 3 (per vol.) or 0.1 mg/cm 2 to 2.0 mg/cm 2 (per area) and overall density of the electrode is within the range of 50 mg/cm 2 to 150 mg/cm 2 (per area), wherein the conductive fibers are selected from the group consisting of a carbon fleece, nickel and stainless steel, and wherein the nickel conductive fibers comprise a nickel foam sheet and the stainless steel conductive fibers comprise stainless steel wool.
