Product Specification

Product name	Hydrogen fuel cell demonstrator
Constitute	consists of PEM electrolysis module, PEM power generation module, air storage tank, air hose, electric fan, base, etc.
material	plastic

1.PEM electrolysis module:
  The electrolysis module consists of anode, cathode and proton exchange membrane. Both poles contain catalysts that accelerate the electrochemical reactions of the electrodes, and proton exchange membranes act as electrolytes. The anode is the positive pole of the power supply, and the cathode is the negative pole of the power supply.
The electrochemical reactions of the two electrodes are:
Cathodic reaction: H+ + 2e- = H2 (1)
Anode reaction: 2O- -4e-=O2 (2)
Due to the catalytic effect of the proton exchange membrane, the number of hydrogen ions and oxygen ions in the water is greatly increased. The positively charged hydrogen ions are attracted by the negative charge of the cathode to reach the cathode and get electrons to be reduced to hydrogen. The positive charge of the positive electrode attracts to the positive electrode and loses electrons to be reduced to oxygen.
2.PEM power generation module:
The power generation module consists of anode, cathode and proton exchange membrane. Both poles contain catalysts that accelerate the electrochemical reactions of the electrodes, and proton exchange membranes act as electrolytes. The anode is the negative pole of the power supply, and the cathode is the positive pole of the power supply. The working principle is shown in Figure 3.
The electrochemical reactions of the two electrodes are:
Anodic reaction: H2 = 2H+ + 2e- (1)
Cathodic reaction: 2H+ + 1/2O2 +2e- = H2O (2)
Overall reaction: H2+1/2O2 = H2O (3)
Since the proton exchange membrane can only conduct protons, hydrogen protons can directly pass through the proton exchange membrane to the cathode, while electrons can only reach the cathode through an external circuit. A direct current is created when electrons flow to the cathode through an external circuit.

Method of use
1. Instrument connection:
Assemble the instrument according to the schematic diagram, add distilled water or deionized water into the two gas storage tanks (the amount of water added is generally not more than 1/3 of the tank depth), cover the top cover of the gas storage tank, adjust the DC power output voltage to dc3v (the DC power supply should be prepared by the user), and connect the power output end with the "+" and "-" interfaces on the top of the instrument electrolysis module with connecting wires (pay attention to the power electrode is not connected incorrectly).
2. Start the experiment:
After checking that the connection is correct, you can turn on the power supply for the experiment. At this time, it is observed that bubbles begin to appear in the transparent air storage tank. There are more and more bubbles, and the reaction in the tank is more and more obvious. After 3-5 minutes, the fan blades rotate. It indicates that hydrogen fuel cell generates electricity.

Product feature and application
It is mainly used to recognize the use of geometric figures in the teaching of mathematics in lower grades.

Maintenance and precautions
1. Only distilled water or deionized water can be used as electrolytic water in the air storage tank, and tap water or mineral water cannot be used as a substitute.
2. Too high power supply voltage will cause damage to the gas making module, and the current supplied by DC power supply to the electrolytic module cannot exceed 0.6A.
3. When the experiment is completed, remove the water from the module. Store the electrolysis module and power generation module in sealed containers.
4. Do not apply external voltage to the voltage output terminal of the power generation module, otherwise the power generation module will be damaged.
5. During the use of the instrument, the product damage caused by falling should be avoided.
6. When using hoses to connect the electrolysis module and the power generation module to the air tank, ensure that all connecting parts and hoses are free of air leakage.
7. Do not disassemble the electrolysis module and the power generation module, otherwise damage may be caused.
