Abstract

A power system is designed for providing reliable electrical power to a facility and/or associated devices. The system includes one or more fuel cells and a circuit adapted to receive power from the one or more fuel cells. The circuit is electrically connected to a device receiving the electrical power from the system. Additionally, the system includes one or more capacitors included in the circuit, and being adapted for maintaining power in the circuit when the one or more fuel cells are temporarily unavailable.

Claims

1. A system for maintaining power to a device of a telecommunications facility, said system comprising:

one or more fuel cells;

a circuit adapted to receive power from said one or more fuel cells;

said circuit electrically connected into said device;

one or more capacitors included in said circuit, said one or more capacitor adapted to be able to maintain power in said circuit when said one or more fuel cells are temporarily unavailable.

2. The system of claim 1, comprising:

an AC power source included in said circuit; and

said one or more capacitors being adapted to be able to maintain power when both of said one or more fuel cells and said AC power source are temporarily unavailable.

3. The system of claim 2, comprising a rectifier for converting an electrical output of said AC source.

4. The system of claim 2, wherein said AC source is electrical power derived from a utility.

5. The system of claim 2, wherein said AC source is a turbine generator.

6. The system of claim 1, wherein said one or more fuel cells are adapted to receive hydrogen from a storage tank.

7. The system of claim 1, wherein said device includes telecommunications equipment.
