  • Patent number: 10105937
    Abstract: The present disclosure provides a vacuum ring for removing bubbles of a laminated assembly and a method for bonding the laminated assembly using the same. The vacuum ring includes an indented portion receiving a laminated assembly to be sealed, and an inner space of the indented portion is in communication with a vacuum source to remove the bubbles. The vacuum ring also includes projection members that are projected inside on the bottom of the indented portion at positions where the projection members are spaced upward from a lower end of the indented portion to receive the laminated assembly, and the projections members are spaced downward from the upper end of the indented portion. Further, the laminated assembly is produced by using the vacuum ring to achieve effective exhaustion by using an aperture formed between side ends of the projection members and the bonding cover.

  • Patent number: 10038200
    Abstract: A method of producing a catalyst including a platinum-transition metal alloy on carbon, more specifically, a method of producing a carbon supported platinum alloy catalyst with high activity and superior durability includes coating a carbon-supported catalyst with an organic polymer as a material for a carbon layer, heat-treating the catalyst under a hydrogen-deficient atmosphere to convert the organic polymer into the carbon layer to prevent growth of catalyst particles caused by heat treatment through the carbon layer, allowing, at the same time, a transition metal supported together with platinum to be diffused into platinum particles to form a catalyst having a core-shell structure including a platinum skin layer on a surface thereof, and removing the carbon layer by ozone treatment after the heat treatment to induce an electrochemical reaction on the surface of the catalyst.
