PURPOSE:To obtain a mechanically strong electrolyte plate while improving the supporting force of an alkaline carbonate electrolyte by allowing said electrolyte to be supported on a uniform porous sintered body comprising long fiber ceramics and fine particle ceramics. CONSTITUTION:In a fuel battery, comprising an anode, a cathode, and an electrolyte plate for supporting an electrolyte arranged between said both electrodes, and electrochemically generating electricity by respectively feeding fuel and an oxidizing agent to a fuel chamber arranged on the anode side and to an oxidizing agent chamber arranged on the cathode side, a porous ceramics sintered body is made by suspending long fiber ceramics and fine particle ceramics into dispersions, filtrating said suspended solution via a screen, forming it into a plate shape while pressing it, and drying and sintering it, and alkaline carbonate is impregnated in said porous veramics sintered body. The long fiber ceramics are mixed in its ratio of 5-65wt% against the fine particle ceramics. |
