  • Publication number: 20230420691
    Abstract: Disclosed is a method of manufacturing a cathode for a solid oxide fuel cell (SOFC) including preparing an electrode composition containing urea, ultrasonically spraying the electrode composition onto a GDC scaffold, and drying the scaffold. By using urea, calcination (?700° C.) after each infiltration cycle can be omitted, the next infiltration cycle is performed immediately after the drying (?100° C.), and thus the cathode manufacturing process time can be greatly reduced. Disclosed is also a solid oxide fuel cell including an anode support, an anode functional layer disposed on the anode support, an electrolyte disposed on the anode functional layer, and a cathode disposed on the electrolyte, wherein the cathode is formed by ultrasonic spraying using an electrode composition containing urea.

  • Patent number: 11761668
    Abstract: The cooling system may dehumidify and cool the indoor air by using the ejector, the ejector membrane, the evaporation chamber, and the indoor dehumidifying membrane. In addition, the coefficient of performance of the cooling system may be improved by cooling the refrigerant using evaporation latent heat generated in the evaporation chamber by the suction force of the ejector and cooling the indoor air using the refrigerant. In addition, by using solar heat to generate high-temperature and high-pressure steam and supply the generated steam to the ejector, energy use efficiency may be improved. In addition, since the temperature of the steam generated in the steam generating portion may be lowered by arranging and using the two first and second ejectors in multiple stages, energy efficiency may be further improved by reducing the consumption of the heat source required for steam generation.
