  • Method of equalizing the pressure drop of fuel cell columns
    Patent number: 11031614
    Abstract: A fuel cell system includes a plurality of fuel cell stacks or columns, each fuel cell stack or column containing a plurality of fuel cells, and at least one pressure drop tool located in a fuel path of at least one first fuel cell stack or column but not in a fuel path of at least one second fuel cell stack or column.
    Type: Grant
    Filed: November 28, 2018
    Date of Patent: June 8, 2021
    Assignee: BLOOM ENERGY CORPORATION
    Inventors: Natarajan Ramanan, Martin Perry, Yashas Keshav, Michael Petrucha, Nilanjana Basu
  • SOFC with cathode exhaust partial bypass of the ATO and additional air cooling of a hotbox
    Patent number: 10957921
    Abstract: One method of operating a fuel cell system including splitting a cathode exhaust from one or more fuel cell stacks in the system into a majority cathode exhaust stream comprising more than 50% of the cathode exhaust and a first cathode exhaust bypass stream, providing the majority cathode exhaust stream to an inlet of an anode tail gas oxidizer (ATO) containing a catalyst and providing the first cathode bypass stream downstream of the catalyst such that it bypasses the catalyst. Another method includes providing an air inlet stream to the SOFC system via a main air inlet, providing the air inlet stream from the main air inlet to a cathode recuperator, and providing a cooling medium to a heat exchanger to cool the cathode recuperator.
