Product parameters Brand: GUYX Size: 20*20*25 Weight: 2.0kg Please contact customer service for detailed parameters. Instrument operation instructions: Install a 1.5V*2 battery in the battery compartment at the bottom of the bottom plate, open the soft rubber plug on the upper part of the gas storage tank, and fill the tank with water. (Note: The water injection should be connected to the lower part of the gas pipe of the fuel cell power generation module on the right side to avoid water. Enter the power generation module to cause damage), cover the rubber plug, and the fuel cell electrolysis module is infiltrated with water for a little time. The wiring connecting the battery box is connected to the fuel cell electrolysis module in red and black, and the small fan connection cable is connected to the power generation module of the fuel cell. During the experiment, bubbles began to appear in the reaction window of the front and back of the electrolysis module, that is, the water was electrolyzed into hydrogen and oxygen, and entered the gas storage tank along the gas pipe in the upper part of the module. Since the whole product is in a closed state, the hydrogen and oxygen gas pipes enter the power generation module, exchange in the proton membrane in the power generation module, generate current and water, and the small fan turns.
