Patent number: 11945915Abstract: A method for synthesizing a pre-hydrolyzed polysilicate, wherein a polysilicate is applied as a reactant when synthesizing the pre-hydrolyzed polysilicate, and the total amount of water added in the reaction system is specified. The method is capable of omitting a condensation reaction by applying a polysilicate as a reactant, thereby significantly shortening synthesis time and reducing production costs when compared with a typical synthesis method in which alkoxysilane-based monomer compound is used as a reactant. In addition, the gelation reaction time and the weight average molecular weight can be easily controlled, and a pre-hydrolyzed polysilicate excellent in storage stability and processability can be synthesized.Type: GrantFiled: November 27, 2019Date of Patent: April 2, 2024Assignee: LG CHEM, LTD.Inventors: Kyu Reon Lee, Kyoung Shil Oh, Jong Hun Kim, Se Won Baek

Patent number: 11936075Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.Type: GrantFiled: December 21, 2021Date of Patent: March 19, 2024Assignee: Korea Institute of Science and TechnologyInventors: Jong Ho Lee, Kyung Joong Yoon, Ji Won Son, Seong Kook Oh, Sang Hyeok Lee, Dong Hwan Kim, Min Jun Oh
