Pure H2 generator Introduction:

   Jinan Mao An Instrument professionally supply PEM/SPE technology H2 generator.


         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.



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, 

3.  Electrolysis of pure water( no adding alkali) to produce high purity(99.999%/99.9995%) 

hydrogen with no corrosion and pollution. 

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

energy. Circle time for changing desiccants is long.

5.  Power consumption is less, electrolysis is efficient

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

7.  Perfect electric control system. stop working in emergency automatically.
