Latest Patents

Yoshimura holds a patent for "Perovskite-type oxide materials containing nickel and iron for air." This solid oxide fuel cell converts chemical reactions between fuel and air or oxygen into electric energy. The design includes a solid electrolyte, an air electrode adjacent to the solid electrolyte, a fuel electrode, and an inter-connector for connecting with other cell units. The air electrode is made of a perovskite-type oxide material with a composition expressed by LnNi.sub.1-x Fe.sub.x O.sub.3 and YNi.sub.1-x Fe.sub.x O.sub.3, where Ln represents lanthanide elements and x ranges from 0.30 to 0.60. These materials provide higher electronic conductivity and a thermal expansion coefficient closer to that of the solid electrolyte compared to conventional materials.
