Abstract
A power system that serves as a source of dedicated back-up power for a cooling system is disclosed. The power system utilizes a plurality of fuel cells, which produce direct current (DC) power. A conversion device, such as an inverter, is used to convert the DC into alternating current (AC) for powering the cooling system. A transfer switch connects the AC power from the inverter to the cooling system. The position of the transfer switch determines the source of AC power for the cooling system.
