The Lab Hydrogen is mainly created through non-Alkaline Proton Exchange Membrane (PEM) type Hydrogen Generators.
This kind of a hydrogen generator is available in sizes ranging from 200 to 4800 cc/min. Please review models below and select the model best suited to the customer's needs.
How do the PEM Process Works?
The Nafion film from Dupont, which is the conductive membrane is coated with catalysts so that it can a Membrane Electrode Assembly or MEA.
This is known by this name because the metal catalyst is fixed on both the sides of the membrane that becomes the positive as well as negative electrodes in the cell. The membrane material that is used itself is a Teflon-based plastic that boasts sulfonic acid groups which are attached to the Teflon structure.
The water is circulated On the oxygen side of the cell or anode, which is used as the feedstock to make the hydrogen and for cooling purposes. The water is split into OXYGEN, PROTONS, and ELECTRONS, when the DC current is applied to the cell. Then the oxygen is swept out of the cell by the circulating water.
The protons then enter the membrane that too, as an electrical charge because they are attracted to the negative electrode or cathode bonded to the opposite side of the membrane.
The oxygen does not mix with the hydrogen and stays on the waterside. The oxygen is swept out of the cell with water circulation. In the mean time, the electrons flow through the power supply circuit outside of the cell and famous Pressurized Leak Detector rejoin the protons at the electrode surface.
They combine to form a molecule of pure hydrogen. This Hydrogen is then famous Pressurized Leak Detector by a back pressure regulator and sent to the respective process.
Is this Hydrogen production safe?
The Hydrogen created under this process is of high pressure and the oxygen is under low pressure, oxygen can NEVER leak into the product hydrogen, that keeps the plant safe.
What kind of Generators are available in the market?
They are mainly available as Hydrogen G200/G400/G600/G600-HP bench-top generators that utilize Proton Exchange Membrane (PEM) cell stack and desiccant dryer to produce UHP hydrogen for laboratory applications.
These systems are capable of sensing demand famous Pressurized Leak Detector as well as adjusting production rate, while maintaining quiet operation.
