摘要

A cathode constituted by a gas and liquid permeable layer bonded to a ion exchange membrane or diaphragm and comprising an electrolyte resistant binder, particles of electrocatalytic material and particles of an electrically conductive material having a higher hydrogen overvoltage than the electrocatalytic particles. Effective porosity is imparted to the layer of particles by means of a sacrificial, pore-forming agent and by leaching out such agent after the particles have been bonded together and the layer formed is in its desired thickness, preferably after it has been deposited upon the diaphragm or the membrane.
