  • Patent number: 8377609
    Abstract: The present invention provides a fuel cell bipolar plate and a method for manufacturing the same, in which a carbon or metal fuel cell bipolar plate is surface-treated with a complex transition metal oxide, which is a main component of a variable resistance heating element having a negative temperature characteristic, so that the bipolar plate can ensure a sufficient amount of heat, required to prevent product water from freezing, by itself in a short time without any external energy, thus improving cold start performance of a fuel cell vehicle at a temperature below zero.

  • Publication number: 20120092363
    Abstract: An apparatus includes a flexible display to display an image; a bending measurement unit to measure a bending value of a portion of the flexible display; and a display control unit to correct an image based on the bending value and to control the flexible display to display the corrected image. In a method for displaying a corrected image, a bending value of a portion of a flexible display is measured, a bent shape of the flexible display is estimated using the bending value, an image is corrected based on the bent shape such that the image is viewed as a planar image of a virtual planar display arranged perpendicular to a viewing direction, and the corrected image is displayed.
