  • Transitioning an electrochemical cell stack between a power producing mode and a pumping mode
    Publication number: 20100285379
    Abstract: A technique includes operating an electrochemical cell stack in a power producing mode, including communicating a fuel flow in an anode chamber of the stack and communicating an oxidant flow in a cathode chamber of the stack. The technique includes halting the oxidant flow and monitoring a voltage of the stack while the oxidant flow is halted, and in response to the voltage decreasing below a predefined threshold, transitioning the stack into an electrochemical cell pumping mode.
