Instructions:
A blue plastic car with a support bracket at the rear that lifts the rear wheels of the car. There is a solar panel with an adjustable single-sided angle near the rear of the trolley, and a fuel cell with two gas and water storage tanks can be installed in the middle. There are two 2mm banana jacks on the panel to connect to the motor on the trolley.
1. Solar power generation
Connect the trolley motor to the solar panel through the banana plug connection. Under the direct sunlight of 60W incandescent, the solar panel generates electricity, and the rear wheel of the trolley can be rotated. The support frame at the rear of the trolley is rotated, and the trolley starts to walk.
2. Solar water electrolysis-hydrogen-oxygen power generation
Pull out the small rubber plug at the middle waist of the gas storage tank with the fuel cell on the trolley, inject distilled water (or pure water) into the lower part of the gas storage tank to the water line with a syringe, and then plug the small rubber plug back into the middle waist , connect the fuel cell and the solar panel with a banana patch cord, under the direct sunlight of a 60W incandescent lamp (or sunlight), after about 30 seconds, you can see the water in the two gas storage tanks slowly rise, and slowly form air in the lower part. The column, that is, solar energy electrolyzes water into hydrogen, and oxygen succeeds.
When the volume of the air column reaches about 8-10ml, the light source can be turned off, and the banana plug wire connected to the solar panel can be inserted into the motor jack of the trolley, and the rear wheels of the trolley can be seen to rotate.
Notice:
It is absolutely forbidden to use electrolyte in the gas storage tank
