Abstract:
1. A method for supplying power to a telecommunications network, the method comprising: providing a primary power source component comprising at least a first proton exchange membrane (PEM), a second parallel PEM, and a reformer for supplying the first and second PEMs with hydrogen fuel, wherein the first PEM generates DC electrical power during a normal operating mode; providing DC electrical power from an energy storage device operable, once the secondary power source component moves from the startup phase of power generation to a steady state operation during a backup mode, stopping the energy storage device from providing the DC electrical power and providing the DC electrical power from the secondary power source component during the backup mode; and providing a DC bus for interconnecting, in parallel, at least the primary power source component, the secondary power source component, the energy storage device, and a programmable logic controller (PLC), wherein the PLC manages switching between the secondary power source component and the energy storage device when the low pressure condition is detected for the secondary power source component.
