How To Build A PEM Hydrogen Generator

Prepare required parts.

Select an aluminum alloy plate as the down-pressing board.

Insert the prepared screws.

Install the insulated gasket.

Pay attention to the position of water inlet and air outlet.

Install titanium alloy positive and negative electrode plates.

Install the sealing silicone gasket.

Install titanium mesh.

1.Titanium mesh shall be placed in the order of high 、medium、 small density.
2.Place them neatly.

Install the microplate.

Align the titanium mesh when placing.

Install DuPont N117 PEM.

The PEM shall be installed carefully to avoid damage.

Install the microplate.

Install the studio sealing silicone gasket.

Install the microplate.

Install the sealing silicone gasket.

Install titanium mesh.

Install titanium alloy positive and negative electrode plates.

Install insulated gasket.

Install aluminum alloy plate.

Install gasket and nut.

Tighten the screws.

Base on the standard compactness and torsion.

Install the air pipe connector and tighten.

water inlet, hydrogen outlet and oxygen outlet shall be distinguished.

Installation completed.

Test after assembly.

Check whether there is resistance and whether there is short circuit between electrode and pressing plate.

Test is normal

Go on power on test

Connect to water pump

Connect the air pipe

Connect to output bus

The output bus plug is connected to the transformer.

The control transfer line connector is connected to the transformer.

The signal line connector is connected to the transformer.

The input bus plug is connected to the transformer.

Connect the water level sensor line of the control transfer line to the tank.

Connect the water pump line controlling the transfer line to the water pump.

Unscrew the upper cover of water gas separator.

Pour in purified water.

Turn on the switch.

During inspection.

1. Whether hydrogen and oxygen are normal(hydrogen outlet) (oxygen outlet).
2. Check whether the voltage and current are normal.
3. Check for water leakage.

If there is no problem in the test, installation is completed.
