Abstract

In the mfr. of electrodes, partic. of cylindrical shape an open-topped and electronically conducting cylindrical grid is placed in a bath containing catalyst particles in suspension and a reduced pressure is created to cause the particles on the surface thereof. The reduced pressure is applied at the upper part of the electrode and maintained during the deposition of the particles.
