What is PEM (SPE) tech in Hydrogen-rich Water

Polymer electrolyte membrane electrolysis

Proton exchange membrane (PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE)that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes. The PEM electrolyzer was introduced to overcome the issues of partial load, low current density, and low pressure operation currently plaguing the alkaline electrolyzer.

Comparision

However, a recent scientific comparison showed that state-of-the-art alkaline water electrolysis shows competitive or even better efficiencies than PEM water electrolysis.[4] This comparison moreover showed that many of the advantages such as gas purities or high current densities that were ascribed to PEM water electrolysis are also achievable by alkaline water electrolysis.

Anode reaction

The half reaction taking place on the anode side of a PEM electrolyzer is commonly referred to as the Oxygen Evolution Reaction (OER). Here the liquid water reactant is supplied to catalyst where the supplied water is oxidized to oxygen, protons and electrons.

Cathode reaction

The half reaction taking place on the cathode side of a PEM electrolyzer is commonly referred to as the Hydrogen Evolution Reaction (HER). Here the supplied electrons and the protons that have conducted through the membrane are combined to create gaseous hydrogen.

Advantages of PEM electrolysis

One of the largest advantages to PEM electrolysis is its ability to operate at high current densities. This can result in reduced operational costs, especially for systems coupled with very dynamic energy sources such as wind and solar, where sudden spikes in energy input would otherwise result in uncaptured energy. The polymer electrolyte allows the PEM electrolyzer to operate with a very thin membrane (~100-200 μm) while still allowing high pressures, resulting in low ohmic losses, primarily caused by the conduction of protons across the membrane (0.1 S/cm) and a compressed hydrogen output.

The polymer electrolyte membrane, due to its solid structure, exhibits a low gas crossover rate resulting in very high product gas purity.

PEM (SPE) tech helps get safer and pure hydrogen-rich water

Hydrogen Water Bottle / Machine / Generaotor is equipped with PEM (SPE) Tech using a proton exchange membrane, which can prevent the waste gas from entering the drinking water, causing water pollution. I often hear that some customers who drink hydrogen water complain that their hydrogen water contains a bad smell. In fact, this is caused by the inability to discharge the electrolytic waste gas. Common waste gases such as ozone and residual chlorine are not recommended for human consumption. It will not only destroy the effect of drinking hydrogen water, but also increase the burden on the body. Therefore, you must choose a hydrogen water generator with PEM (SPE) tech to ensure that you get pure hydrogen water.

So as long as PEM (SPE) Tech is equipped, can it guarantee safety and health?

No, an excellent exhaust system will achieve good results. The H2 Life hydrogen water bottle uses an active bottom exhaust system to completely exhaust the exhaust gas. The unique bottom exhaust design can immediately release ozone and chlorine gas. In addition, it is compatible with DuPont 117 proton exchange membrane. Waste gas will not enter of drinking water 100%! The H2 Life hydrogen water bottle report shows that its hydrogen purity is higher than 99.99%, and it does not contain any ozone, chlorine and heavy metals! So check out the H2 Life hydrogen water bottle and see why it is probably the best SPE / PEM hydrogen water generator in the market today.
