Mobile-power system utilizing propane generator, fuel cell and super capacitors
View Patent ↗The present invention is a mobile-energy generating system capable of providing redundant direct current power. It comprises a reciprocating engine and generator having dual fuel capability, a fuel cell, commercial electrical power hookups, and capacitors used for bridging purposes. Back-up fuel for the engine and fuel for the fuel cells are stored in propane and hydrogen storage tanks, respectively.
1. A power supply system capable of producing redundant direct current (DC) power, said system comprising:
a generation subsystem producing a first source of alternating current (AC);
a means for converting said first source of AC into a first source of DC;
a device adapted to consume hydrogen to generate a second source of DC; and,
at least one capacitor to bridge when switching between said first source of DC and said second source of DC.
2. The system of claim 1 , wherein said generation subsystem includes a reciprocating engine producing an output motion and a generator adapted to utilize said output motion to produce said first source of AC.
3. The system of claim 2 wherein said reciprocating engine is adapted to combust natural gas and propane.
4. The system of claim 1 wherein said system is adapted to receive AC from a utility.
5. The system of claim 1 wherein said device comprises at least one fuel cell.
6. The system of claim 5 wherein said fuel cell comprises at least one proton exchange membrane.
7. The system of claim 5 wherein said at least one fuel cell receives said hydrogen from a plurality of storage tanks.
8. The system of claim 1 wherein said means for converting said first source of AC into a first source of direct current (DC) comprises at least one rectifier.
9. The system of claim 1 wherein said at least one capacitor is adapted to be selectively charged from said first source of DC.
10. The system of claim 1 wherein at least said generation subsystem, said means for converting said first source of AC to said first source of DC, said device to generate said second source of DC, and said at least one capacitor are located on a mobile platform.
11. The system of claim 10 wherein said mobile platform is connected to a base transceiver station (BTS) for providing electrical power thereto.
12. The system of claim 1 wherein said means to switch between said first source of DC and said second source of DC comprises a control system having the programmable logic necessary to determine the appropriate source to utilize.
