A method for manufacturing a fuel cell electrolyte matrix comprises the steps of providing a fuel electrode and oxidizing electrode respectively coated with a catalyst layer on one side, forming a layer of powdery electrolyte-resistive material on the surface of at least one of the catalyst layers, coating a paste layer prepared from acid electrolyte and powdery electrolyte-resistive material on the powder layer or catalyst layer of the fuel electrode and/or the powder layer or catalyst layer of the oxidizing electrode, tightly superposing the fuel electrode and oxidizing electrode on each other with the paste layer and powder layer interposed therebetween, thereby forming an electrolyte matrix between both electrodes.
