Product Name:
Hydrogen Fuel Cell Experimenter
Material: metal, plastic
Product size: 125*100*85mm

Precautions:
1). Do not apply external voltage to the battery voltage output terminal, otherwise it will damage the fuel cell.
2) Store the PEM fuel cell in a sealed container (such as a ziplock bag).
3) When using a hose connection, make sure that all connecting parts and hoses do not leak air
4) Do not disassemble the PEM fuel cell and electrolyzer, otherwise it may cause damage.Please read this manual carefully before using this instrument. The user shall be responsible for the losses caused by the reversed polarity of the electrodes and the liquid in the battery.

Instructions:During the experiment, add water to the hydrogen generator bottle to the water level. The water temperature is preferably about 30 degrees. Then add the hydrogen generator in the vial to the water, tighten the cap and connect the hydrogen generator bottle to the hydrogen inlet of the battery with a pipe. After a few minutes, connect the wires to the battery, the motor starts to work, and the current and voltmeter indicate something.The liquid in the hydrogen production bottle must not flow into the battery to avoid damage.
