Summary: This study presents a hydrogen production system that combines anodic and cathodic H-2 production from low-potential aldehyde oxidation and the hydrogen evolution reaction, respectively, at a low voltage of about 0.1V.

The assembled electrolyser requires only about 0.35 kWh of electricity input per m(3) of H-2, providing a promising avenue for the safe, efficient and scalable production of high-purity hydrogen.
