A rigid, monolithic, porous gas diffusion element which is formed of a body of solid particles and which is comprised of a partially coated, permeable ceramic substrate is disclosed. The substrate consists essentially of a porous first ceramic material, has an apparent porosity of from about 35 to about 50 percent, and has a minimum active pore size of from about 40 to about 120 microns; and it is partially coated with a coating which consists essentially of a second ceramic material has an apparent porosity of from about 35 to about 55 percent, and has a minimum active pore size of from about 10 to about 40 microns. The minimum active pore size of the substrate is from about 2 to about 5 times as great as the minimum active pore size of the coating.
