Abstract
The present invention is a modular power system using a fuel cell as a back-up power supply. The system includes lithium-metal-polymer (LMP) batteries to bridge and also for backup power if necessary. The entire system is preassembled ready for use so that it is available to a new or expanding site upon delivery. The total number of modular units used can simply be aggregated to meet additional power demanded.
