  • Electrochemical device for syngas and liquid fuels production
    Patent number: 9631284
    Abstract: The invention relates to methods for creating high value liquid fuels such as gasoline, diesel, jet and alcohols using carbon dioxide and water as the starting raw materials and a system for using the same. These methods combine a novel solid oxide electrolytic cell (SOEC) for the efficient and clean conversion of carbon dioxide and water to hydrogen and carbon monoxide, uniquely integrated with a gas-to-liquid fuels producing method.
    Type: Grant
    Filed: March 14, 2014
    Date of Patent: April 25, 2017
    Assignees: Colorado School of Mines, Alliance for Sustainable Energy, LLC
    Inventors: Robert J. Braun, William L. Becker, Michael Penev

  • Handling an electrochemical cell stack
    Publication number: 20070259257
    Abstract: An assembly includes an electrochemical cell stack and an outer insulation layer. The electrochemical cell stack includes a port to form a releasable connection with a stack handling mechanism. The outer insulation layer substantially covers the stack and an opening through the insulation layer exposes the port for connection with the stack handling mechanism.

  • Recuperative exhaust gas processor for a fuel cell system
    Publication number: 20070248859
    Abstract: Fuel cell systems and methods are disclosed, where the systems include a burner configured to receive a first gas that is exhausted from a fuel cell and to combust the first gas to provide a second gas, and a heat exchanger in fluid communication with the burner, the heat exchanger being configured to receive the second gas from the burner and to transfer heat from the second gas to additional first gas that is exhausted from the fuel cell.

  • Purging a fuel cell system
    Publication number: 20070154746
    Abstract: A technique that is usable with a fuel cell system includes shutting off a fuel flow to an anode chamber of a fuel cell stack of the system. The technique includes providing an oxidant flow to fuel passageways of the fuel cell system until fuel is significantly purged from the system.
