An uninterruptible power supply system comprising a source of a utility power signal, a source of hydrogen, a fuel cell stack, first and second input circuits, an output circuit, and a control circuit. The fuel cell stack converts the hydrogen into a fuel cell output signal. The first input circuit is operatively connected to the utility power signal and outputs a first AC input signal based on the utility power signal. The second input circuit operatively is connected to the fuel cell output signal and generates a second AC input signal based on the fuel cell output signal. The output circuit is operatively connected to the first and second input circuits and outputs at least one output signal based on one of the first and second AC input signals. The control circuit operatively is connected to the fuel cell stack, the first input circuit, the second input circuit. The output circuit controls whether the output signal is generated based on the utility power signal or hydrogen. |
