Abstract: The present invention relates to a technique for manufacturing a unit cell for a solid oxide fuel cell (SOFC) which can improve the output of the unit cell of the solid oxide fuel cell, without occurring cost due to an additional process. The unit cell of the solid oxide fuel cell, comprises: a fuel electrode support body; a fuel electrode reaction layer; an electrolyte; and an air electrode, wherein the fuel electrode support body is made from an NiO and YSZ mixed material, the fuel electrode reaction layer is made from a CeScSZ and NiO mixed material, the electrolyte is made from a CeCsSZ material, and wherein the air electrode is made from an LSM and CeScSZ mixed material.

Abstract: Provided is a method for synthesizing air electrode powder, which uses instead of an organic solvent lanthanum-nitrate, strontium-nitrate, cobalt-nitrate, and iron-nitrate, which are affordable and can undergo water-based synthesis, by controlling additional mol ratio and a synthesis temperature of a chelate agent and an esterification reaction accelerating agent instead of complex process controlling conditions, such as a hydrolysis condition and pH in order to control particle shape.

Abstract: Proton-conducting hybrid glass and a method for manufacturing the same. The proton-conducting hybrid glass has CsPWA created inside the pores of borosilicate glass. The proton-conducting hybrid glass can be used as an electrolyte for electrochemical devices, such as fuel cells and sensors. When the proton-conducting hybrid glass is used as an electrolyte membrane for a fuel cell, excellent thermal and chemical stability is realized in the range from a high temperature to an intermediate temperature of 120° C. A high proton conductivity of 10?3S/cm or higher and good catalytic activity are realized. In addition, high volumetric stability and excellent moisture retention characteristics in high and intermediate temperature ranges are achieved.
