Power system for a telecommunications facility
View Patent ↗An energy generating system for a telecommunications facility includes a hydrogen fuel supply system. The hydrogen fuel supply system includes a source of liquid hydrogen which uses a high pressure expansion tank along with additional storage tanks. The system also incorporates first and second stage heat exchangers. The first stage exchanger is used to benefit from the endothermic reaction created when liquid hydrogen transforms into vapor. The cooling provided from this state change is transferred into a second medium which is delivered into a second stage heat transfer device and then used for air conditioning purposes. The system also includes a hydrogen generator which may be used to create AC power by combusting vaporous hydrogen.
1. A power supply system for providing electrical power to a telecommunications facility, said facility containing telecommunications equipment, said system comprising:
a fuel cell which is operable to produce electrical power for the purpose of operating said telecommunications equipment, said fuel cell adapted to be powered by hydrogen supplied from a source, said source including
a first storage vessel for meeting immediate hydrogen needs; and
a second storage vessel for meeting the normal operating needs;
said first vessel maintaining hydrogen at higher pressures than said second vessel;
a source of liquid hydrogen;
a vaporizing system for converting said liquid hydrogen to vapor for delivery to at least one of said first and second vessels; and
a heat transfer device which absorbs heat into at least one of liquid and vaporous hydrogen from a fluid heat transfer medium, said fluid heat transfer medium being useable for cooling purposes.
2. The system of claim 1 , wherein said fuel cell includes a proton exchange membrane.
3. The system of claim 1 , wherein said fluid heat transfer medium is a refrigerant.
4. The system of claim 1 , wherein said heat transfer device includes a first heat transfer device and a second heat transfer device, said second heat transfer device supplying cooling for an air conditioning system of the telecommunications facility.
