  • Variable fuel cell power system for generating electrical power
    Patent number: 8691454
    Abstract: The present invention provides an apparatus and methods for variably supplying power from a stand-alone fuel cell power supply system including a power conversion unit, a power switching unit and a load control unit. Preferably, a controller manages system configuration to switch the loads, the power conversion and the delivery between the two without reducing capacity by redundantly backing up each individual portion with a bank of at least two modules for each unit. Preferably, controller actuated devices are triggered automatically in response to monitors that sense performance operating parameters and detect values operating outside a threshold range.
    Type: Grant
