  • Solid oxide fuel cell stack with reduced-leakage unit cells
    Patent number: 10790519
    Abstract: Solid oxide fuel cell stacks and methods of sealing a planar solid oxide fuel cell. Unit cells within the stack each include a metal frame with a periphery that can both provide a support surface for a membrane electrode assembly, as well as form a fluid-tight seal with a bonded separator plate. The separator plate includes a peripheral lip that bounds a cell-receiving cavity such that a volumetric region is formed within the separator plate to receive at least a portion of the membrane electrode assembly to create a fluid-tight pathway for at least one of the reactants that is being introduced to a corresponding anode layer or cathode layer of the membrane electrode assembly.
    Type: Grant
    Filed: June 5, 2018
    Date of Patent: September 29, 2020
    Assignee: Saudi Arabian Oil Company
    Inventors: Sai P. Katikaneni, Inyong Kang, Jinwoo Park, Hyundal Song, Hyunbae Park, Byungwook Park
