Patent number: 8690974Abstract: A pyrolytic hydrogen generator comprising a pressure vessel containing a plurality of cardboard receptacles for the thermally decomposable hydrogen generating material and an associated ignition system. Also, a modular pellet tray assembly for use in the generator comprises a plurality of trays having pellet holders and associated igniters and held in a stack by support rods that also provide electrical connectivity to the trays. Also, a pellet tray assembly comprises a plurality of pellet holders, wherein some of more outwardly disposed pellet holders contain only outwardly facing vents and are fired first. Also, the generator has an array of hydrogen generating elements arranged side by side and separated from one another into cells by partitioning provided with directional venting that only permits laterally exiting gases to vent outwardly. Alternatively, the elements can be separated into cells by a baffle system comprising gas confining and gas venting elements, which may be heat conductive.Type: GrantFiled: October 14, 2008Date of Patent: April 8, 2014Assignee: Qinetiq LimitedInventors: Darren Paul Scattergood, Graham Manton, Gareth Thomas Flegg, Robert John Vere Churton, Philip Nicholas Barnes, William Ranulf Slee

Patent number: 6506511Abstract: A multi-element fuel cell system comprises a substantially cylindrical former (2), a rechargeable hydrogen fuel source (3) and a plurality of fuel cell elements (4). The former comprises a series of interconnecting modules each perforated to allow passage of fuel to the fuel cell elements. Each fuel cell element (4) is positioned radially outwardly of the former (2) and is provided with channels, arranged to receive and direct fuel gas, an anode current collector, a gasket (12), a first diffusion backing layer (8), a membrane electrode assembly (10), a second diffusion backing layer (9) and a cathode current collector (11). The cathode current collector applies even compression to the fuel cell element, such that good electrical contact is maintained within each fuel cell element. The fuel cell elements are electrically connect in series via respective anode and cathode current collectors and then capped at each end of the former for connection to equipment.Type: GrantFiled: October 26, 2000Date of Patent: January 14, 2003Assignee: Qinetiq LimitedInventors: John B Lakeman, Ranulf Slee, Kevin J Green, John M Cruickshank
