electrolyser that works with an alkaline environment at the membrane interface provided by the immobilized positively charged functional groups on the polymer backbone or on pendant polymeric side chains (anion exchange membrane)

electrolyser performing electrolysis of water where the reaction occurs in a solution composed of water and liquid electrolyte (30% KOH) between two electrodes and when a sufficient voltage is applied between the two electrodes, at the cathode water molecules take electrons to make OH⁻ ions and H2 molecule
