ABSTRACT:
A method of making a highly porous cermet electrode on a solid electrolyte. The solid electrolyte is coated with noble metal and glass particles and heated to fuse the glass particles. The coated electrolyte is then annealed to form a separately leachable borate phase in the glass. That phase is then leached from the coating to leave a highly porous silica matrix throughout which the conductive particles are exposed.
