Enhancing energy efficiency in water electrolysis with electrodes
In water electrolysis, water molecules (H₂O) are split into hydrogen (H₂) and oxygen (O₂) using an external electric current. The process occurs in two half-reactions: hydrogen evolution at the cathode and oxygen evolution at the anode.
These reactions are energy-intensive, with overall system efficiency striving on minimizing energy losses, also occurring at the electrodes due to overpotentials, ohmic resistance, or inefficient catalysis.
Improving the efficiency of these reactions requires electrodes
with high catalytic activity, low resistance, and robust durability under operating conditions. This is where De Nora’s innovative electrode solutions make the difference
