What is PEM technology

Hydrogen rich water products use SPE (Solid poly electrolytic) technology, and electrolysis plate has PEM (proton exchange membrane) membrane, so they produce PURE and SAFE hydrogen rich water, without by products such as OZONE, CHLORINE and other OXIDES.

What is PEM technology?

PEM : PROTON EXCHANGE MEMBRANE

1). Water at the anode provides source of H+ ions. 

2). PEM permits migration of H+ ions from anolyte to cathode. 

3). At cathode, H+ ions combine with electrons from the power supply (reduction reaction) to form H atoms which pair-up to form H2 gas. 

4). Oxygen gas produced at the anode (through oxidation of hydroxide) must be vented (alternatively, chlorine gas may be produced instead of oxygen, depending on source water chloride levels). 

5). PEM contains an electrolyte (SPE, solid polymer electrolyte, an electrical conductor), and therefore electrolysis is not dependent on source water minerals. 6). Lower electrical resistance between anode & cathode results in less voltage drop and more efficient electrolytic production of H2. 

7). Because pH of the drinking water is not raised, this design does not encourage the precipitation of calcium which greatly reduces the degree of limescale buildup within the system.
