20080289955Electrolysis - Solid oxide stacks used as fuel cells generate electricity from hydrogen or other sources. By an electrolysis process such standard fuel cells can be operated in order to create hydrogen or other electro chemical by-products. Unfortunately stacks generally operate at relatively high temperatures which will be difficult to sustain purely on economic grounds. In such circumstances less efficient operation can be achieved at lower temperatures where the air-specific resistance is higher by balancing with the electrical power input in order to cause the disassociation required. In such circumstances by provision of an incident heat source, whether that be through a heat exchanger heating the compressed air flow, or recycling of a proportion of exhaust from the stack, or combustion of a product from stack disassociation the result will be a sustaining electrolysis operation reducing the amount of expensive electrical supply required to achieve dissociation.11-27-2008
20080292925Pre-reformer - A pre-reformer (11-27-2008
20080314741Electrolysis apparatus - An electrolysis apparatus comprises an electrolysis cell to electrolyze a first fluid to generate a product fluid. The electrolysis apparatus also comprises a fuel cell to electrolyze an electrolytic fluid and to heat a second fluid. The electrolysis apparatus also includes a fluid transfer arrangement to transfer the heated second fluid from the fuel cell to the electrolysis cell to provide heat to drive the electrolysis of the first fluid in the electrolysis cell.12-25-2008
20090042082Fuel cell arrangement - A fuel cell arrangement comprises at least one fuel cell module, each fuel cell module comprises a plurality of fuel cells. Each fuel cell module is hollow and defines a chamber. Each fuel cell module is arranged within an inner vessel and the inner vessel is arranged within an outer pressure vessel. Means to supply oxidant is arranged to supply oxidant to the space within the inner vessel so as to supply oxidant to the cathode electrodes. Means to supply fuel is arranged to supply fuel to the chamber in each fuel cell module so to supply fuel to the anode electrodes. The outer pressure vessel is protected from the high temperature environment of the fuel cells by the inner vessel. The outer pressure vessel forms the main pressure containment of the arrangement and operates at a lower temperature and operates with a greater safety margin than a single pressure vessel arrangement.02-12-2009

20100203413FUEL CELL AND A METHOD OF MANUFACTURING A FUEL CELL - A solid oxide fuel cell comprises a porous anode electrode, a dense non-porous electrolyte and a porous cathode electrode. The anode electrode comprises a first member and a plurality of parallel plate members extending from the first member. The cathode electrode comprises a second member and a plurality of parallel plate members extending from the second member. The plate members of the cathode electrode inter-digitate with the plate members of the anode electrode and the electrolyte fills the spaces between the first and second members and the parallel plate members of the anode electrode and the cathode electrode.08-12-2010
20110129934METHOD FOR INFERRING TEMPERATURE IN AN ENCLOSED VOLUME - A method for inferring temperature in an enclosed volume containing a fuel/oxidant mixture, the method comprises placing at least one wire in the enclosed volume. The at least one wire having an identifiable property wherein the identifiable property of the at least one wire changes from a first identifiable state at a temperature below the auto-ignition temperature of the fuel/oxidant mixture to a second identifiable state at a temperature above the auto-ignition temperature of the fuel/oxidant mixture, and determining if the identifiable property of the at least one wire has changed from the first identifiable state to the second identifiable state and hence if the temperature in the enclosed volume is above the auto-ignition temperature of the fuel/oxidant mixture.06-02-2011
