  • Solid oxide electrolyzer system including air bypass
    Patent number: 12264398
    Abstract: An electrolyzer system includes a splitter configured to split a first air inlet stream into a bypass air stream and a second air inlet stream, a stack of electrolyzer cells configured receive steam and the second air inlet stream and output a product stream containing hydrogen and an oxygen exhaust stream, such that the bypass air stream is configured to bypass the stack, and a product cooler heat exchanger configured to cool the product stream using the first air inlet stream.
    Type: Grant
    Filed: May 3, 2024
    Date of Patent: April 1, 2025
    Assignee: BLOOM ENERGY CORPORATION

  • ELECTROLYZER SYSTEM WITH STEAM GENERATION AND METHOD OF OPERATING SAME
    Publication number: 20240425993
    Abstract: An electrolyzer system includes a steam generator configured to generate steam, a stack of solid oxide electrolyzer cells configured to generate a hydrogen stream using the steam received from the steam generator, and a water preheater configured to preheat water provided to the steam generator using heat extracted from oxygen exhaust output from the stack.
