Abstract
A process and an apparatus for manufacturing electrocatalytic electrodes. The process comprises the steps of immersing a substrate in a plating bath containing metal ions and electrocatalytic material in particles form, such as Ni, NiAl, and CoAl, among others. Electric current is established in the bath inducing a deposition of metal on the substrate by reduction of metal ions and, simultaneously, the cell containing the plating bath is inverted periodically to cause a recurrent migration of the particles of electrocatalytic material, under the effect of gravity, toward the substrate, in order to build-up a layer of electrocatalytic material on the substrate, the particles of the electrocatalytic material being fixed on the substrate by the reduction of metal ions.
