Abstract

A fuel cell system is described for providing primary, auxiliary, or backup power to one or more loads upon or after the occurrence of a power demand or outage condition. A controller senses the power demand or outage condition, and, responsive there to, operatively engages one or more fuel cells to provide power to the one or more loads.
