Patents by Inventor Yong Gyun BAE

Yong Gyun BAE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10840533
    Abstract: This application relates to a separator for a fuel cell and a fuel cell stack with improved durability, which contains the same, particularly to a solid oxide fuel cell stack. Specifically, this application allows an oxidizer and a fuel to flow in a counter-flow manner and a cross-flow manner in the fuel cell stack by forming an outlet manifold and an inlet manifold to have a specific shape, location and size in the separator. As a result, interlayer peeling, microcracking, etc. are prevented because no variation in temperature, reactant concentration, power, etc. occurs between each unit cell and the power density per unit volume is significantly improved because the volume is minimized.

  • Patent number: 10707071
    Abstract: A substrate processing apparatus includes a chamber providing a space in which a substrate is processed, a first substrate support within the chamber and configured to support the substrate when the substrate is loaded into chamber, a second substrate support within the chamber and configured to support the substrate in a height greater than the height in which the first substrate supports the substrate, a first supply port through which a supercritical fluid is supplied to a first space under the substrate of a chamber space, a second supply port through which the supercritical fluid is supplied to a second space above the substrate of the chamber space, and an exhaust port through which the supercritical fluid is exhausted from the chamber.

  • Publication number: 20200212456
    Abstract: Disclosed is a fuel cell with improved thermal distribution in a stack including two more unit cells stacked therein. The fuel cell includes a stack including the two more unit cells and separators each having manifolds formed through four sides thereof, a first chamber having an internal space so as to receive air and fuel from the outside and to transfer the air and fuel to a second chamber and so as to receive the air and fuel discharged from the stack and to discharge the air and fuel to the outside, a second chamber having an internal space so as to receive the air and fuel from the first chamber and to transfer the air and fuel to the stack, and a connecting part connecting the first chamber to the second chamber so as to allow the air and fuel to flow to the second chamber from the first chamber.

  • Publication number: 20200075966
    Abstract: The present disclosure provides a separator for a fuel cell, including a central part with a rectangular shape, and a surrounding part disposed to surround the central part, wherein the surrounding part includes an outlet manifold positioned at a pair of edges of the central part, which are opposed each other, and an inlet manifold positioned along a side of the central part to be adjacent to another edge except for the pair of edges at which the outlet manifold is positioned, and the central part includes a plurality of guide patterns that are spaced apart from each other to guide fluids introduced through the inlet manifold toward the outlet manifold.
