The effects of electrolytic voltage,electrolyte flow rate and electrolyte composi-tion on the current density during hydrogen sulfide electrolysis were studied,and the stability of electrode materials was investigated.The results show that the hydrogen production rate increa-ses with the increase of electrolytic voltage.When the electrolytic voltage is 1.1 V,the hydrogen production power consumption is 2.6 kW·h/m3,and the current density can reach 163 mA/cm2.In the electrolyte,the current density increases first and then decreases with the increase of H+concentration.When the electrolyte H+concentration is 8 mol/L,the current density rea-ches the maximum.The current density increases with the increase of Fe2+concentration in so-lution,and the change is more obvious when the electrolytic voltage is higher.In addition,the electrolyte flow velocity can effectively reduce the diffusion effect when it's greater than 200 L/h;The experiment also shows that the graphitic electrode exhibits good stability in the electrolyt-ic process,which provides a guarantee for the long-term stable operation of the electrolytic sys-tem.
