Abstract

Activated cathodes were prepared from papermaking techniques for use in a membrane type chlor-alkali cell. These cathodes consisted of a nickel fiber matrix, which entrapped a platinum electrocatalyst supported on activated carbon fiber. Following optimizations of the void volume, thickness, catalyst loading, carbon support, and substrate–support ratio, these cathodes performed at an overpotential of only 58 mV @ 3 kA m−2 in a cell containing 30 wt% NaOH at 80 °C. In addition to I/V performance, cathodes were characterized for catalyst dispersion and support surface area. When testing was discontinued, activated cathodes had demonstrated stability for greater than 60 days in a custom cell designed for continuous, steady-state operation.
