[0030] During the use of the utility model, the photovoltaic panel 1 is used to convert solar energy into electrical energy to provide power for the electrolytic cell 2; the electrolytic cell 2 decomposes water into hydrogen and oxygen by receiving the electrical energy generated by the photovoltaic panel 1; the pipeline 3 is used to transport the hydrogen and oxygen generated by the electrolytic cell 2 to the storage tanks respectively; the storage tanks are used to store hydrogen and oxygen.

[0031] First, the photovoltaic panel 1 installed outdoors converts solar energy into direct current electrical energy. The photovoltaic cells in the photovoltaic panel 1 are devices that convert light energy into electrical energy. When sunlight shines on the photovoltaic cells, photons excite the semiconductor material in the photovoltaic cells, causing electrons to transition from the valence band to the conduction band and generating current.

[0032] The DC electric energy is supplied to the power supply component of the electrolyzer 2. In the electrolyzer 2, the electric energy passes through the water electrolysis device, which includes an anode and a cathode, for electrolyzing water molecules.

[0034] Working principle, the working principle of the household photovoltaic hydrogen production device is mainly based on the photovoltaic effect and the water electrolysis principle. The photovoltaic effect enables solar energy to be converted into electric energy, while the water electrolysis principle enables electric energy to be converted into hydrogen and oxygen. The specific process of achieving the sealing effect at the elbow. To ensure the safety of hydrogen during transmission and prevent hydrogen leakage, a good sealing effect needs to be achieved at the elbow of the device. The specific process is as follows:

The sealing gasket 902 is placed at the elbow connection, and through the pressing force, it is closely attached to the elbow surface to prevent hydrogen leakage. At the same time, a sealing ring 901 can be set below the sealing gasket 902 to further enhance the sealing effect.

[0036] During the installation process, it is necessary to ensure that the positions of the sealing gasket 902 and the sealing ring 901 are correct and apply an appropriate pressing force. After the installation is completed, a leakage test needs to be carried out to ensure that the sealing effect at the elbow meets the requirements. If any leakage is found, timely adjustment and repair are required.
