Is it possible like the electrolysis of any metal ion as chloride salt. You will produce hydrogen at the cathode by reduction of H+ and chlorine at the anode by oxidation of Cl-. To perform this operation you need proper electrodes. Especially for the anode, proper means corrosion resistant electrodes such as Ni or Ti. However even stainless steel might be used because, even if it undergoes corrosion with release of iron ions in the electrolyte, the iron ions themselves promote the reduction of H+ on the cathode surface by lowering the overpotential. From a technological point of view you need also to remove the chlorine produced at the anode. For this purpose there is a need of some kind of piping where the chlorine goes from the electrodes. Someone also used special hallow anodes able to convey the produced Chlorine.
You can significantly reduce cell operating potential by running in "ODC" mode. This stands for oxygen de-polarized cathode. By flowing air or pure O2 over your cathode you can change the cathode reaction from H2-evolution to O2-reduction, this changes the theoretical operating potential from >1V to ~0.5V. Thus achieving operational current densities at around 1V instead of 2V - representing significant power savings.
