Hydrogen Water Electrolysis
Hydrogen water electrolysis splits deionised water across a solid proton-exchange membrane: water is oxidised at the anode, protons migrate through the membrane, and hydrogen is reduced at the cathode before being dissolved into the water volume.
- Proton transport occurs in a solid polymer, not in a potassium hydroxide solution.
- Hydrogen output tracks applied current, so production is modulated electrically.
- Hydrogen and oxygen are separated at the cell, so the oxygen stream is not dissolved.
Cell mechanism
A membrane electrode assembly is supplied with DC. Water is oxidised at the anode, releasing oxygen and protons; protons cross the membrane and are reduced to hydrogen at the cathode. Because the membrane also separates the two gas streams, hydrogen is available for dissolution without a downstream separation step.
Dissolution behaviour
Hydrogen is only sparingly soluble in water. Concentration rises with partial pressure and contact time and falls with temperature, agitation and exposure to headspace, which is why dissolved figures are quoted with a stated measurement time and container condition.
