  Hydrogen Generator

(high pressure: 0--7BAR, 0--100psi)


Product Description


                                           Past CE


        SPE series hydrogen generator, is with world advanced SPE/PEM  technology. PEM full name is Proton Exchange Membrane. Also called SPE technology ( solid polymer electrolyte). 

Through. electrolysis pure water( no need to add chemicals) to produce high purity hydrogen. 

This machine is light, high effective, 

energy saving and environmental protection. And world advanced patent right products.


0--300ml/min, 0--500ml/min, 99.999%/99.9995% , 0--7bar pressure,


TH-300/500/1000 Advantages                                                            

1.  PEM technology---Proton Exchange Membrane


2.  The PEM electrodes, as the core of the product, are highly active catalytic electrode with 

nearly zero distance between the electrodes, which is formed by integrating composite catalyst 

with ion membrane with high electrolytic efficiency.


3.  Plural-electrode and multiunit electrolysis cell structure. 

     Excellent chemical technological process properties of heat and mass transfer.


4.  Electrolysis of pure water( no adding alkali) to produce high purity      (99.999%/99.9995%) hydrogen with no corrosion and pollution. 


5.  Voltage of cell is low, electronic resistance in the electrolysis cell is little, could greatly 

saving  energy. Circle time for changing desiccants is long.


6.  Power consumption is less, electrolysis is efficient


7.  Hydrogen output flow under stable pressure. Gas produced on demand, no storage.

1. World advanced "SPE" technology ( solid polymer electrolysis)


2. No chemical(KOH or NaOH ) inside. Directly electrolysis pure water. Protect GC column.


3. Use proton exchange membrane from USA "Dupont" brand


4. Inside use silicon rubber rings ( lower sulphur content), increase gas output purity, guarantee GC basic line stable.


5. Output pressure and gas output display both use integration control.


6. Automatically water level control, when short of water, machine auto stop working, greatly 

protect electrolysis cell lifetime.


7. Could meet all brands GC working requirement at home and abroad.
