Currently, PEM cell technology is the most promising, gradually replacing traditional alkaline electrolysis. PEM (Proton Exchange Membrane) is a proton exchange semipermeable membrane made of special high-tech materials that can conduct protons – hydrogen atoms nuclei – through themselves. The PEM cell is used to separate hydrogen from electrolysis by-products such as oxygen and other impurities (e.g. ozone and chlorine). Therefore, despite high purity requirements for initial electrolyte solution, user does not need to spend additional money on additional hydrogen produced purification.
Electrolysis cell is a system’s core. A proton exchange membrane electrolyser separates reagents and transports protons by blocking direct electron path through the membrane. PEM fuel cells use a solid polymer membrane (a thin plastic film) that is permeable to protons when saturated with water, but does not conduct electrons.
The hydrogen generated in the cell enters a hydrogen separator, where residual moisture is separated, and the hydrogen enters a final stage of purification – PSA dehydration columns. After, hydrogen with 99.9998% purity is supplied to customer’s technological process.
