  • Measurement device for measuring voltages along a linear array of voltage sources
    Patent number: 9647283
    Abstract: A measurement device for measuring voltages along a linear array of voltage sources, such as a fuel cell stack, includes at least one movable contact or non-contact voltage probe that measures a voltage of an array element.
    Type: Grant
    Filed: February 20, 2015
    Date of Patent: May 9, 2017
    Assignee: BLOOM ENERGY CORPORATION
    Inventors: John Matthew Fisher, Ian Russell, Chad Pearson, Robert Hintz, Nathan Ben Erlin, David Edmonston, Stephen Couse, Michael Dubuk
  • Measurement device and method for determining fuel cell stack size variations
    Patent number: 9490490
    Abstract: A measurement device for measuring voltages along a linear array of voltage sources, such as a fuel cell stack, includes at least one movable voltage probe that measures voltage transitions along an array element. The measured voltage is used to determine a distance of travel of the at least one voltage probe along the fuel cell stack from the speed of the probe and the timing of the transitions.

  • Fuel Cell System Hot Box Insulation
    Publication number: 20140162162
    Abstract: A method of insulating a base portion of a fuel cell system including pouring an insulation that can be poured to fill at least 30 volume % of a base portion cavity of the fuel cell system housing through an opening in a sidewall of the housing. The base portion cavity of the housing is located between a bottom wall of the housing and a stack support base plate located in the housing. The stack support base plate supports one or more columns of fuel cell stacks.

  • Systems and Methods for Bypassing Fuel Cells
    Publication number: 20140087286
    Abstract: Embodiment methods for bypassing a fuel cell in a fuel cell stack include identifying a fuel cell to bypass and connecting a conductive bypass to the fuel cell stack such that the bypass electrically connects a first interconnect in the fuel cell stack and a second interconnect in the fuel cell stack and electrically bypasses the identified fuel cell. Further embodiment methods include applying a conductive sealing material to the fuel cell stack such that the conductive sealing material seals a cathode inlet or outlet of the identified fuel cell and such that the conductive sealing material electrically bypasses the identified fuel cell.
