Jinan Mao An Instrument Co.,Ltd professionally produced hydrogen generator in China for 30 years. Focus on world advanced technology SPE/PEM H2 generator and PEM electrolytic cell production.Only electrolysis pure water( no need to add alkaline) to produce high purity hydrogen.

We have machine H2 flow rate from 0--4000ml/min, H2 output purity reaches 99.999%, H2 output pressure is 0--2MPa

Mostly important, inside PEM cell already been produced by us for 30 years. Very durable to be used for 5--10 years. USA “ Dupont” brand PEM membrane, platinum as catalyst, 100% Titanium electrode etc, reasonable structure etc. All these guarantee our hydrogen generator is very durable to be used for years without any problem.
