Abstract (en)
[origin: WO2008070725A1] Various embodiments of a power supply solution for a telecommunications site and/or network provide either a primary source or a backup source of electrical power 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.
