${\mathrm{OH}}^{-}$ions react with ${\mathrm{N}}_2{\mathrm{H}}_4$ at the anode to form ${\mathrm{N}}_2(\mathrm{g})$ and water, releasing 4 electrons to the anode.

At the cathode, ${\mathrm{N}}_2{\mathrm{H}}_4$ breaks to ${\mathrm{N}}_2(\mathrm{g})$ and nascent hydrogen released at the electrode reacts with oxygen to form water.

At the cathode, molecular oxygen gets converted to ${\mathrm{OH}}^{-}$.

Oxides of nitrogen are major by-products of the electrochemical process.
