Hydrogen balloon and how to operate it

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen balloon capable of floating in the sky for a long period of time, and an operation method of the same.SOLUTION: The hydrogen balloon comprises an airbag 4 which stores hydrogen H and floats a gondola 2 in the sky using buoyancy of hydrogen H, a water tank 10 which stores water W, an electrolysis device 12 which electrolyzes water W into hydrogen H and oxygen O and a hydrogen utilization device 14 which generates water W from oxygen O in the air and hydrogen H in the airbag. Hydrogen H generated by the electrolysis device 12 is stored in the airbag 4 in the gas state as it is, and is re-used for increase of buoyancy or operation of the hydrogen utilization device 14, oxygen O generated by the electrolysis device 12 is released into the air and water W generated by the hydrogen utilization device 14 is stored in the water tank 10 and is re-used for electrolysis.SELECTED DRAWING: Figure 4
