  • CO-FLOW / COUNTER-FLOW FUEL CELL OR ELECTROLYSIS CELL
    Publication number: 20130171538
    Abstract: A cell stack with cells adapted to operate as either fuel cells or electrolysis cells comprises cells with a counter-flow of the anode gas relative to the cathode gas on a first part of each cell and a co-flow on a second part of each cell which evens out the temperature profile of the cell and cell stack relative to a co-flow or a counter-flow cell.

  • Fabrication process for package with light emitting device on a sub-mount
    Patent number: 7732234
    Abstract: A method of fabricating a package with a light emitting device includes depositing a first metallization to form a conductive pad on which the light emitting device is to be mounted and to form one or more feed-through interconnections extending through a semiconductor material that supports the conductive pad. Subsequently, a second metallization is deposited to form a reflective surface for reflecting light, emitted by the light emitting device, through a lid of the package. Deposition of the second metallization is de-coupled from deposition of the first metallization.

  • Grating structures and methods of making the grating structures
    Patent number: 6762880
    Abstract: New grating structures include a bonded transmission grating structure. The grating structure is encapsulated by two pieces that are bonded together. In addition, a new method of making grating structures includes forming wells with an aspect ratio (depth:width) of at least 3:1, 7:1 or greater. Such grating structures can be used to form gratings with high diffraction efficiencies for both TE and TM polarizations of light.
