POWER SYSTEM FOR A TELECOMMUNICATIONS NETWORK
First Claim
1. A power system for a telecommunications network, comprising:
- a first subsystem for providing DC electrical power to a first telecommunications network location, including at least one proton exchange membrane operable to produce DC electrical power as well as an energy storage device for storing the DC electrical power; and
a second subsystem for providing DC electrical power to a second telecommunications network location, including at least one microturbine generator operable to produce AC electrical power, at least one rectifier operable to convert the AC electrical power from the at least one microturbine generator to DC electrical power, and at least one proton exchange membrane operable to produce DC electrical power.

Abstract
A reliable, end-to-end power supply solution for components of a telecommunications network provides either a primary source or a backup source of electrical power at various telecommunications sites for reliable operation of telecommunications equipment. One subsystem of the power supply solution includes one or more proton exchange membrane type fuel cells and an energy storage device for storing DC electrical power produced by the fuel cells. Another subsystem includes one or more microturbine generators, one or more rectifiers for converting AC electrical power produced by the microturbine generators to DC electrical power, and one or more proton exchange membrane type fuel cells for producing DC electrical power. The power supply solution ensures that voice and data traffic is reliably handled by a telecommunications network in situations where commercial electric utilities fail to supply power at certain points along the network.

13. A method for supplying power to a telecommunications network, comprising:
-
at a wireless communication site utilizing a base transceiver system, providing DC electrical power from at least a first proton exchange membrane, and providing DC electrical power from an energy storage device operable during at least a startup phase of power generation of the at least a first proton exchange membrane; and at a telecommunications exchange or a point of presence server, providing AC electrical power from at least one microturbine generator operational and converting the AC electrical power from the at least one microturbine generator to DC electrical power via at least one rectifier during a first operational phase, and providing DC electrical power from at least a first proton exchange membrane during a second operational phase, wherein the first operational phase and the second operation phase do not substantially overlap. - View Dependent Claims (14, 15, 16, 17)
