  • Patent number: 11088379
    Abstract: An electrolyte membrane of a membrane-electrode assembly has improved chemical durability. The electrolyte membrane includes a composite, which includes an antioxidant in an ionic state and a first ionomer surrounding the antioxidant. The composite is dispersed in a second ionomer, which is a polymer matrix. A manufacturing method for the electrolyte membrane includes preparing an antioxidant solution, mixing the antioxidant solution and a first ionomer dispersion solution, drying the mixture to produce a composite having an antioxidant and a first ionomer surrounding the antioxidant, introducing and mixing the composite with a second ionomer dispersion solution, and applying that mixture to a substrate and drying the mixture to manufacture an electrolyte membrane.

  • Patent number: 10367277
    Abstract: A multi-earth terminal includes: a body having a hook piece and a hook rib, which are formed on an outer edge of the body; a barrel coupled with a wire; and a connector interconnecting the body with the barrel. Two or more bodies are stacked vertically and coupled to each other. When the two or more bodies are stacked vertically and coupled to each other, each of the two or more bodies includes the hook rib and the hook piece so that the hook rib of a first body that is located at an upper side of the vertically stacked bodies is inserted into and engaged with the hook piece of a second body that is located at a lower side of the vertically stacked bodies.

  • Patent number: 10351125
    Abstract: A method for stabilizing an engine clutch control includes transmitting an engine clutch operation start command from a controller to an engine clutch system, the engine clutch system including an engine clutch, detecting a hydraulic pressure generated during the operation of the engine clutch system, carrying out an oil leakage judgment mode using the controller to determine whether the hydraulic pressure is a normal hydraulic pressure where the operation of the engine clutch is available or if the hydraulic pressure an abnormal hydraulic pressure where the operation of the engine clutch is unavailable, and changing an operation mode to an emergency operation mode wherein the operation of the engine clutch is stopped in case of abnormal hydraulic pressure, and carrying out an operation mode change by operating the engine clutch in a case of normal hydraulic pressure, based on a control by the controller.

  • Patent number: 9744839
    Abstract: A transmission for a hybrid vehicle includes a planetary gear set including at least three rotary members of which one is connected to an engine. A first anti-rotator selectively restricts rotation of the rotary member connected to the engine. A first motor generator is connected to another one of the rotary members of the planetary gear set. A second motor generator is connected to the remaining one of the rotary members of the planetary gear set. An output shaft has a first output gear thereon, which is externally engaged with the rotary member connected to the first motor generator. A second anti-rotator selectively restricts rotation of the rotary member connected to the second motor generator.

  • Patent number: 9252437
    Abstract: An apparatus preventing over-cooling of a fuel cell is provided that includes a cooling fluid manifold which is mounted to a stack of the fuel cell and through which cooling fluid flows therethrough. End plates are arranged on both ends of the stack of a fuel cell, and at least one protrusion is provided on one surface of each of the end plates. The at least one protrusion is disposed inside a cooling fluid manifold to reduce the flow amount of the cooling fluid which flows in and out between the separating plates through the cooling fluid manifold.
