  • Oxygen plenum configurations of components in low cost planar rechargeable oxide-ion battery (ROB) cells and stacks
    Patent number: 9620832
    Abstract: An ROB stack (10?) contains a plurality of stacked ROB cells (10) made from: thin metal bipolar housings (13) having air inlets and exits and horizontal channels for feeding air between the inlets (16) and exits (17), the channel having top ridges and also grooves (25) for containing active material (34); a porous air electrode (21/39) next to the air channels allowing air contact; a metal electrode (36); and an oxygen ion transfer membrane (37) acting as electrolyte; wherein the plurality of all the assemblies form vertical air inlet and outlet plenums.

  • Current bus and power lead assemblies for solid oxide fuel cell generators
    Patent number: 7651801
    Abstract: A solid oxide fuel cell generator (10) is made which contains bundles (14) of solid oxide fuel cells (36), a bus bar unit (128) in adjacent contact with the fuel cell bundles, where the bus bar unit (128) can pass electrical current, the bus bar unit (128) containing flat inner plate sections (130) adjacent the fuel cell bundles, outer solid nickel bar (134) and with solid, U-shaped nickel strap take-off connections (136) between the plates and bar; and a power lead (140) electrically connected to the outer solid nickel bar, where the flat inner plate sections (130) and solid U-shaped nickel strap take-off connections (136) pass electrical current generated in the fuel cell bundles through the bus bar units (128).
