Latest Patents

One of his latest patents involves a solid oxide fuel cell that features a composition gradient between the electrode and electrolyte. This invention discloses a method of creating a laminate structure consisting of an electrolyte layer made from an oxide ion conductor material, specified by La A Ga Co O, and an air electrode layer made from an electron conductor material, specified by La A CoO. An intermediate layer of an electron and ion mixed conductor material, specified by La A Ga B Co O, is interposed between these layers. The laminate is sintered to integrate the layers and is subjected to heat treatment, allowing elements to diffuse through the interface between adjoining layers. This continuous change in composition at each interface enhances the cell's performance, reducing issues such as cracks, distortion, and delamination. Additionally, the increased reaction area in the air electrode leads to improved cell efficiency.
