  • Technique for designing and manufacturing solid oxide fuel cell having improved output capability in mid to low temperature
    Patent number: 9318766
    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.

  • METHOD FOR SYNTHESIZING AIR ELECTRODE POWDER FOR MID- AND LOW- TEMPERATURE SOLID OXIDE FUEL CELL ACCORDING TO SOL-GEL PROCESS
    Publication number: 20150001442
    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.
