MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517089620 A) filed by Niterra Co. Ltd., Aichi, Japan, on Sept. 19, for 'sensor element, gas sensor, and method for manufacturing sensor element.'
Inventor(s) include Ito Kazuma; and Nanya Wakako.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "[Problem] To provide: a sensor element which has improved detection accuracy by satisfactorily burning unburnt gas in a gas to be measured, and in which a decrease in the response speed of a sensor is suppressed; a gas sensor; and a method for manufacturing a sensor element. [Solution] A sensor element 10 which detects a specific gas in a gas to be measured comprises: a first electrode 41 and a second electrode 42, which are provided on a solid electrolyte layer 30; and at least one porous layers 80 which is interposed between the outside and one of the first electrode and the second electrode so that the gas to be measured, which is introduced from the outside toward at least one of the first electrode and the second electrode, passes therethrough. At least one porous layer is a catalyst layer 81 which supports particles 90 of one or more noble metals that are selected from the group consisting of Pt, Pd and Rh. When an X-ray absorption fine structure analysis is performed, an absorption intensity Ip at an absorption end of the noble metal particles supported by the catalyst layer is between an absorption intensity Im at the absorption end of the pure metal of the noble metal particles and an absorption intensity Io at the absorption end of an oxide of the noble metal particles."
The patent application was internationally filed on Dec. 25, 2023, under International application No.PCT/JP2023/046425.
