Publication number: 20240139718Abstract: The present invention is a perovskite metal oxide catalyst substituted with metal ions for reducing carbon deposition, a method for producing the same, and a process for performing a methane reforming reaction using this catalyst. The catalyst is produced in which Ni in ionic form is substituted at a portion of the Ti site of SrTiO3, MgTiO3, CaTiO3, or BaTiO3, which is a multi-component metal oxide having a perovskite structure. Then, various methane reforming reactions (steam-methane reforming, dry reforming of methane, catalytic partial oxidation of methane) may be efficiently and economically performed using this catalyst. The nickel-substituted perovskite metal oxide catalyst has a structure in which Ni2+ is substituted in the perovskite lattice structure. Thus, the metal oxide catalyst has advantages in that carbon deposition thereon does not occur, and thus, the catalyst has a high catalytic stability and may be used for a long time.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Chang Hyun KO, Ji Yoon Jeon, Jeong Woo Yun, Eun Gyong Park

Publication number: 20240128484Abstract: A fuel cell system and a method of controlling the system are provided. The fuel cell system includes: a fuel cell having a plurality of cells to generate power through a reaction between hydrogen supplied to an anode space and oxygen supplied to a cathode space; a power storage device to be charged with power generated by the fuel cell or discharged to supply power; and a controller. The controller recirculates hydrogen, diffused from the anode space to the cathode space, into the anode space by supplying power charged in the power storage device to the fuel cell when the power generation of the fuel cell is stopped. The controller is configured to control whether to supply the power to the fuel cell based on a pressure measured in the anode space and voltages of the cells that constitute the fuel cell.Type: ApplicationFiled: April 18, 2023Publication date: April 18, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Ji Hoon Ryu, Jae Sung Ryu, Jong Hyun Lee, Yei Sik Jeon, Young Wook Cheong

Patent number: 11918981Abstract: The present invention relates to a perovskite metal oxide catalyst substituted with metal ions for reducing carbon deposition, a method for producing the same, and a process for performing a methane reforming reaction using this catalyst. According to the present invention, a novel type of catalyst is produced in which Ni, iron or cobalt in ionic form is substituted at a portion of the Ti site (B-site) of SrTiO3, MgTiO3, CaTiO3 or BaTiO3, which is a multicomponent metal oxide having a perovskite (ABO3) structure. Then, various methane reforming reactions (e.g., steam-methane reforming (SMR), dry reforming of methane (DRM), catalytic partial oxidation of methane (CPOM), etc.) may be efficiently and economically performed using this catalyst. The nickel-substituted perovskite metal oxide catalyst according to the present invention has a structure in which Ni2+, Co2+, Fe2+, Co3+ or Fe3+ is substituted in the perovskite lattice structure.Type: GrantFiled: November 6, 2017Date of Patent: March 5, 2024Assignee: INDUSTRY FOUNDATION OF CHONNAM NATIONAL UNIVERSITYInventors: Chang Hyun Ko, Ji Yoon Jeon, Jeong Woo Yun, Eun Gyong Park
