Publication number: 20200119366Abstract: A ceramic composite for a fuel cell anode is disclosed. A method for preparing the metal-ceramic composite for a fuel cell anode, the metal-ceramic composite including (i) metal catalyst nanoparticles and (ii) a mixed-conductive ceramic, comprising (A) co-depositing a metal catalyst raw material and a mixed-conductive ceramic by physical vapor deposition. The metal catalyst raw material is present in an amount such that the content of the metal catalyst nanoparticles in the metal-ceramic composite is significantly lower than in conventional metal-ceramic composites. The presence of a small amount of the metal catalyst nanoparticles in the metal-ceramic composite minimizes the occurrence of stress resulting from a change in the volume of the metal catalyst and provides a solution to the problem of defects, achieving improved life characteristics. Also disclosed is a method for preparing the metal-ceramic composite.Type: ApplicationFiled: December 12, 2019Publication date: April 16, 2020Inventors: Ji-Won SON, Jung hoon PARK, Jongsup HONG, Hyoungchul KIM, Kyung Joong YOON, Jong Ho LEE, Hae-Weon LEE, Byung Kook KIM

Patent number: 9966624Abstract: Provided is a method for manufacturing a sintered body for an electrolyte and an electrolyte for a fuel cell using the same. More particularly, the following disclosure relates to a method for preparing an electrolyte having a firm thin film layer by using a sintered body having controlled sintering characteristics, and application of the electrolyte to a solid oxide fuel cell. It is possible to control the sintering characteristics of a sintered body through a simple method, such as controlling the amounts of crude particles and nanoparticles. In addition, an electrode using the obtained sintered body having controlled sintering characteristics is effective for forming a firm thin film layer. Further, such an electrolyte having a firm thin film layer formed thereon inhibits combustion of fuel with oxygen when it is applied to a fuel cell, and thus shows significantly effective for improving the quality of a cell.Type: GrantFiled: November 8, 2016Date of Patent: May 8, 2018Assignee: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Kyung Joong Yoon, Seung-Hwan Lee, Mansoo Park, Jongsup Hong, Hyoungchul Kim, Ji-Won Son, Jong Ho Lee, Byung Kook Kim, Hae-Weon Lee

Patent number: 9893367Abstract: Provided is an interlayer for a thin electrolyte solid oxide cell, a thin electrolyte solid oxide cell including the same, and a method of forming the same. In various embodiments, functional elements (a fuel electrode, an electrolyte and a cathode) of the solid oxide cell are formed by means of a thin film process, and thus a nanostructure of the catalyst is not seriously lost due to agglomeration, different from a powder process. Thus, it is possible to accomplish catalyst activation according to a high specific surface area.Type: GrantFiled: January 5, 2017Date of Patent: February 13, 2018Assignees: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGY, GLOBAL FRONTIER CENTER FOR MULTISCALE ENERGY SYSTEMSInventors: Ji-Won Son, Thieu Cam Anh, Jongsup Hong, Hyoungchul Kim, Kyung Joong Yoon, Jong Ho Lee, Hae-Weon Lee, Byung Kook Kim

Publication number: 20170365861Abstract: A metal-ceramic composite for a fuel cell anode is disclosed. In the metal-ceramic composite, the content of the metal is greatly reduced and the intervals between the metal particles are maintained constant, achieving improved activity and conductivity. The metal-ceramic composite includes a metal catalyst raw material and a mixed-conductive ceramic. The metal catalyst raw material is present in an amount such that the content of the metal catalyst nanoparticles in the metal-ceramic composite is significantly lower than in conventional metal-ceramic composites. The presence of a small amount of the metal catalyst nanoparticles in the metal-ceramic composite minimizes the occurrence of stress resulting from a change in the volume of the metal catalyst and provides a solution to the problem of defects, achieving improved life characteristics.
