  • Methods and systems for fuel cell stack sintering and conditioning
    Patent number: 9837670
    Abstract: Systems and methods for sintering and conditioning fuel cell stacks utilizing channel guides, baffles, and internal compression systems are provided. Sintering and conditioning may be performed utilizing a fuel cell column cartridge assembly and fuel cell stacks may be sintered and conditioned at the system level during the same annealing cycle on the same support.
    Type: Grant
    Filed: May 19, 2015
    Date of Patent: December 5, 2017
    Assignee: BLOOM ENERGY CORPORATION

  • Solid oxide fuel cell stack heat treatment methods and apparatus
    Patent number: 9142845
    Abstract: Systems and methods are provided for fuel cell stack heat treatment. An eductor may be used to recycle air into the air inlet stream or to recycle fuel into the fuel inlet stream. An eductor may also be used to exhaust air away from the furnace. The stack heat treatment may include stack sintering or conditioning. The conditioning may be conducted without using externally supplied hydrogen.

  • Cell and Cell Block Configurations for Redox Flow Battery Systems
    Publication number: 20150125768
    Abstract: Embodiments of an electrochemical flow cell stack are disclosed. A plurality of frame layers may each have a peripheral gasket channel configured to receive a gasket material. The gasket channel may surround a recessed area having a size and a structure configured to receive an insert layer. Each of the plurality of frame layers may include at least one void area defining a first half-cell chamber of a flow cell. A plurality of insert layers may each be nested within a corresponding frame layers. Each insert layer may include at least one void area defining a second half-cell chamber of the flow cell. A flow cell may be formed by one of the plurality of frame layers and one of the plurality of insert layers.
