  • Publication number: 20190305351
    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: 10415134
    Abstract: Disclosed is a crucible that exhibits stable evaporation efficiency and durability with respect to Al, is used in an evaporation source of an electron-beam evaporator, and includes a storage unit, which includes a wall and a bottom and in which a deposition material is placed, and a wetting prevention unit that includes another wall, which is taller than the wall of the storage unit, and another bottom, and is combined with an exterior of the storage unit. The wetting prevention unit is provided so that only the wall of the storage unit is wet with Al, and accordingly, the lifespan of the crucible is lengthened. Further, contact with the ceramic material in order to prevent wetting is minimized, thereby preventing a reduction in the physical properties of the thin film due to the impurities mixed with the deposited Al.

  • Patent number: 6339934
    Abstract: Apparatus for mounting an air conditioning unit upon the roof of a vehicle for providing conditional air to the interior of the vehicle. A frame is contained within an opening formed in the roof and the unit is mounted upon the frame so that the supply air opening and the return air opening of the unit communicate with the interior of the frame. A one-piece floor panel is contained in the frame upon which an adjustable partition is seated which divides the interior of the frame into two separate compartments. The base of the partition is secured to the floor panel and a movable top section is closed against the pan of the unit so that the supply air can move through one compartment and return air through the other compartment. The top section of the partition is adjustable and is furnished with thick resilient seals so that the mounting frame can be utilized in vehicles having different roof depths.
