Independent power supply system of hydrogen fuel cell

Abstract

The invention discloses an independent power supply system of hydrogen fuel cell. The system comprises a closed shell, a display and a three-layered metal frame; a hydrogen fuel cell galvanic stack, a hydrogen storage bottle and a radiator fan are arranged at the bottom layer of the three-layered metal frame; an inverter and a gas passage control element are arranged at the middle layer of the three-layered metal frame; the inverter is electrically connected with the gas passage control element; a DC / DC (direct current / direct current) converter, a controller and a storage battery are arranged on the upper layer of the there-layered metal frame; the storage battery is electrically connected with the inverter, the DC / DC converter and the controller respectively; and the controller is electrically connected with the display, the radiator fan and the air passage control element respectively. The independent power supply system of the hydrogen fuel cell provided by the invention can overcome the defects that in the prior art, the structure is unreasonable, the thermal radiation is large, the specific power is low, the air supply is single, the carrying is inconvenient and the like, and realize the advantages of reasonable structure, small thermal radiation, high specific power, much air supply and convenience in operation.

Description

technical field [0001] The invention relates to the field of clean energy, in particular to a hydrogen fuel cell independent power supply system. Background technique [0002] In the field of clean energy, the portable hydrogen fuel cell power system is a portable UPS backup power technology that uses the hydrogen in the hydrogen storage device to electrochemically react with the oxygen in the air through the fuel cell to release electric energy to drive electrical appliances. [0003] Hydrogen fuel cell power system, compared with general portable UPS backup power (for example: battery power is limited, and the charging time is very long, fuel generators have great noise pollution and environmental pollution), hydrogen fuel cell power system is clean and environmentally friendly , larger power output, less noise and so on. [0004] However, the hydrogen fuel cell power supply system in the prior art is not well designed, and the problems of heat dissipation and humidificat...

AI Technical Summary

Problems solved by technology

[0004] However, the hydrogen fuel cell power supply system in the prior art is not well designed, and the problems of heat dissipation and humidification have not been well solved, resulting in large heat radiation, low specific power, single gas source, and blindly relying on gas cylinders to supply gas will lose Portability

[0005] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art such as unreasonable structure, poor heat dissipation performance, poor humidification performance, large heat radiation, low specific power, single gas source and inconvenient to carry.
