Abstract: Disclosed herein are a system and a method for the production of hydrogen. The system advantageously combines an independent high temperature heat source with a solid oxide electrolyzer cell and a heat exchanger. The heat exchanger is used to extract heat from the molecular components such as hydrogen derived from the electrolysis. A portion of the hydrogen generated in the solid oxide electrolyzer cell is recombined with steam and recycled to the solid oxide electrolyzer cell. The oxygen generated on the anode side is swept with compressed air and used to drive a gas turbine that is in operative communication with a generator. Electricity generated by the generator is used to drive the electrolysis in the solid oxide electrolyzer cell.

Abstract: A system and method for operating a fuel cell, including reacting a fuel with an oxidant within the fuel cell to produce electricity and reaction products comprising steam. The fuel is fed through the fuel cell, wherein a concentration of the steam increases in the first direction through the fuel cell. The direction of fuel-flow through the fuel cell is altered or reversed upon satisfying a condition, thereby altering the concentration gradient of steam in the fuel cell and providing for removal of carbon deposition with the fuel cell. Such reversal of fuel flow may also provide an exhaust from the fuel cell that can regenerate an external or adjacent hydrocarbon reformer.

Abstract: An electrochemical cell structure comprises a conductive base, that defines a plurality of holes, and a grid layer disposed on the conductive base. A porous support layer at least partially interpenetrates the grid layer to at least one of the conductive base or the holes.

Abstract: A method of making an electrode structure is provided. The method includes disposing an electrocatalytic material on an electrode, applying heat to the electrocatalytic material to form a volatile oxide of the electrocatalytic material, and applying a voltage to the electrode to reduce the volatile oxide to provide a number of nano-sized electrocatalytic particles on or proximate to a triple phase boundary, where the number of nano-sized electrocatalytic particles is greater on or proximate to the triple phase boundary than in an area that is not on or proximate to the triple phase boundary, and where the triple phase boundary is disposed on the electrode.

Abstract: The present invention provides interconnection links between modules in a switch node. A redundant physical link couples the modules and a dual state data packet routing tag is used to identify which link is active. A standard tag received from an application device is converted to the dual state data packet routing tag, after the data leaves the application device so the interconnection link routing is essentially invisible to the application layer.

Abstract: A method is provided for increasing the life expectancy of a solid oxide fuel cell by preventing cathode poisoning due to chromium volatilization. Chromium hydroxide and oxyhydroxide formation and evaporation are prevented by continuously drying the cathode feed gas to low moisture levels. Power generation configurations that minimize the energy penalty associated with cathode gas drying are also disclosed.

Abstract: An electrolyzer assembly comprises at least one electrolyzer cell including at least two electrodes and an electrolyte interposed therebetween. The electrolyzer assembly further comprises an interconnect structure in intimate contact with at least one of the two electrodes or the electrolyte. The interconnect structure includes at least one flow channel initially defined by a removable sacrificial material, wherein the interconnect structure is configured to provide support for the electrodes and the electrolyte.
