[0026] Among them, such as Figure 1 As shown, the water recycling and processing module includes a water recycling and processing box 106, a water filtration system 1061 and a pure water tank 1062; the water recycling and processing box 106 is connected to the water filtration system 1061 through a recovery pipe, and the water in the water filtration system 1061 enters the pure water tank 1062 after filtration.

The principle of fuel cell power generation: the basic working process of hydrogen fuel cell power generation is to send hydrogen to the anode plate (negative electrode) of the fuel cell. After the action of the catalyst, an electron in the hydrogen atom is separated, and the hydrogen ion (proton) that has lost the electron passes through the proton exchange membrane and reaches the cathode plate (positive electrode) of the fuel cell, and recombines with the oxygen atom and hydrogen ion to form water; there are four groups of detachable raw material boxes 105; in power generation mode, the alcohol-based raw material is transported to the methanol reforming hydrogen production recombinator module 1042 through the methanol water raw material buffer tank 1041.

The hydrogen fuel cell power generation module 1044 then undergoes an electrochemical reaction to generate electricity. A hydrogen fuel cell is an electrochemical device consisting of a positive electrode, a negative electrode, and an electrolyte. The positive and negative electrodes are connected by the electrolyte, forming an electrochemical system where hydrogen and oxygen react. The basic operating principle is that hydrogen is delivered to the anode plate (negative electrode) of the fuel cell. A catalyst acts to separate an electron from the hydrogen atom. The de-electronized hydrogen ion (proton) passes through the proton exchange membrane and reaches the cathode plate (positive electrode) of the fuel cell, where it recombines with the oxygen atom and hydrogen ion to form water. Two sets of water recovery and processing tanks 106 are provided.

[0030] Among them, 3-5 movable energy storage batteries 2014 are provided, and the spare movable energy storage batteries 2014 are stored in the battery pack storage cabinet 202. The power transformation and distribution energy storage cabinet 201 is connected to the battery pack storage cabinet 202 through the slide rail 301.

[0034] The specific usage and function of this embodiment are as follows:
[0035] In the present invention, when the device is used, the alcohol-based raw material is transported to the methanol reforming hydrogen production recombiner module 1042 through the methanol-water raw material buffer tank 1041 of the modular methanol hydrogen production power generation cabinet 104.
