Abstract

PURPOSE:To hold bubbling pressure and a gas utilization factor so high by filling up electrolyte resisting fine powder kneaded paste consisting of a binding agent and an electrolyte in a recess and a cracked part on the surface of a matrix layer formed on a catalyst layer surface of an electrode. CONSTITUTION:Matrix paste containing stable electrolyte resisting fine powder against phosphoric acid and a binding agent is applied to the surface of a layer 2 of a pair of porous electrodes 3 formed with a catalyst layer on one side, and a sintered type matrix layer 1 after heat treatment. Next, phosphoric acid is impregnated with this layer 1, and the electrolyte resisting fine powder and kneaded paste 8 consisting of the binding agent and the phosphoric acid is filled up in a recess 6 and a cracked part 7 produced on the surface of the layer 1 for their recoverability. And, the electrode 3 is joined to a matrix surface so as to cause it to be opposed and pressurized, thereby unitizing them in one. With this constitution, bubbling pressure and any drop in a gas utilization factor is checked, thus such a matrix as improving the extent of cell capacity so sharply is manufacturable.
