Hydrogen Generation Plant
Hydrogen is not for the future, it is a reality.
On-site supply of hydrogen to metal refining industry and using high purity oxygen
It is the way of enhancing the capability of cost saving
It is a facility to distribute, supply and use the compressed gas containers that are from the generated hydrogen and oxygen from the water. The highly purified hydrogen can be used for cooling semi-conductors and turbines. Moreover, the oxygen can be used for food science such as synthesis of protein.

ㆍEM Solution is a leading company of manufacturing hydrogen generator in domestic market
through its R&D for many years.
ㆍIt secured electrolysis system operating technology by using solar generating electricity.
ㆍIt obtained patent of electrolytic stack structure and design which is core technology of
hydrogen generator.
Alkali type hydrogen generation plant (purity module embedded)
It is possible to supply safe and stable hydrogen gases with an eco-friendly system which does not discharge any green-house gases. Moreover, low manufacturing cost of hydrogen leads to cost reduction. There are no risks of storing high pressure gases and introduction of an automatic control system for all manufacturing process of hydrogen, enhance users’ convenience. However, EMS ensures its stability and safetiness through certified durability test.

Mechanism of Hydrogen Generator
-
-
The alkali type hydrogen generator uses electrolyte of potassium
hydroxide and the separation film is installed between positive and
negative poles to prevent them from being mixed.
Water is electrolyzed to produce hydrogen ion (H+) and
hydroxyl ion (OH-), and the hydrogen ion reacts with
the electrons to generate hydrogen gases at negative pole.
The hydroxyl ion (OH-) passes through the ion exchange membrane
and move to positive pole in order to generate the oxygen gas.
