Patent ID: 8329350

Claim:
An electric power generator comprising: a rack having multiple module bays wherein some of the bays are power conversion module bays and fuel cell bays; at least one fuel cell stack mounted in one of the fuel cell bays; a metering and power conversion module mounted in one of the power conversion module bays and comprising at least one internal power conversion device electrically coupled to the stack and configured to convert the voltage level and/or current type of some of the electricity produced by the stack such that the generator can simultaneously output electricity at multiple voltage levels and/or current types; and an output bus assembly comprising multiple output buses each electrically communicative with at least one of the power conversion module bays and each output bus having a specified power conversion rating and at least one outlet for coupling to at least one electrically powered device; wherein each output bus occupies a different position in the power conversion module bays, and the metering and power conversion module has an output terminal positioned to electrically couple only to the output bus having the same power conversion rating when the metering and power conversion module is mounted in the power conversion module bay.
