    Abstract: A method of controlling a fuel cell system includes applying alternating current (AC) signals to an individual fuel cell. The AC signals have a plurality of different frequencies. A voltage across the individual fuel cell is determined at each of the plurality of different frequencies. An impedance characteristic of the individual fuel cell is determined based at least in part on the voltage across the individual fuel cell at each of the plurality of different frequencies. The individual fuel cell is controlled based at least in part on the impedance characteristic.

    IPC: G06F1/26

    Abstract: Systems and methods include a power module comprising at least one fuel cell generator for powering a load, and a bypass mechanism having a first, normally-open fast-acting switch that closes in 1-250 msec, and a second, normally-open switch in parallel with the first switch, the bypass mechanism being electrically connected between the load and a second power source, such as a grid source, where the first switch is configured to close in response to a fault event such that when the first switch is closed power to the load is provided from the second power source through the first switch, and the second switch closes after a predetermined time such that power to the load from the second source is provided through the second switch. Additional methods and systems include providing power to a plurality of loads using fuel cell power generators.
