Patent number: 11011759Abstract: A redox flow battery includes a flow path frame provided with a flow path conveying an electrolyte introduced into a fixing frame having a flow path for introducing and discharging an electrolyte supplied from outside. The flow path frame is provided with an inflow path connected to the flow path of the fixing frame and an outflow path discharging the electrolyte to an impregnation part conveying the electrolyte to a reaction surface of a membrane, thereby preventing leakage of the electrolyte that is caused by a difference between supply pressure and circulation pressure of the electrolyte.Type: GrantFiled: September 30, 2015Date of Patent: May 18, 2021Assignee: STANDARD ENERGY CO., LTD.Inventors: Bu Gi Kim, Ki Hyun Kim, Da Young Kim

Patent number: 10665882Abstract: A redox flow battery according to the present invention is provided with a battery module including a battery cell or a stack, and a pair of electrolyte tanks, and a replacement of a pump is applied for each battery module to transfer electrolyte to the battery cell and the stack such that shunt current is reduced. In addition, each battery module is provided with the pair of the electrolyte tanks such that a transfer distance of the electrolyte can be reduced, and a fluid controller using pressure instead of a pump for each module such that power required for driving the pump can be reduced and efficiency of the battery can be improved.Type: GrantFiled: April 28, 2018Date of Patent: May 26, 2020Assignee: Standard Energy Co., Ltd.Inventors: Bugi Kim, Kihyun Kim, Bumhee Cho, Damdam Choi

Patent number: 10468706Abstract: A REDOX flow battery or fuel battery includes a reactant storing and collecting unit for preventing leakage of a reactant. The battery includes two end plates and a stack that is disposed between the end plates and includes one or more unit cells. The reactant storing and collecting unit for preventing leakage of a reactant is disposed inside or outside the stack. According to the present invention, sealing reliability of the REDOX battery or fuel battery is dramatically improved. In addition, although a reactant or a product leaks from the stack, the reactant or the product may not leak to an outside of the battery but is collected before leaking to the outside. Therefore, the battery according to the present invention has an advantage of easy maintenance.Type: GrantFiled: December 31, 2014Date of Patent: November 5, 2019Assignee: STANDARD ENERGY CO., LTD.Inventors: Bu Gi Kim, Da Young Kim
