From: A clean and membrane-free chlor-alkali process with decoupled Cl2 and H2/NaOH production
In situ differential electrochemical mass spectrometry of H2 and Cl2 production. a DEMS curve of the H2 evolution and the c corresponding chronopotentiometry curve (cell voltage vs. time) at an applied current of 100 mA. b DEMS curve of the Cl2 evolution and the d corresponding chronopotentiometry curve (cell voltage vs. time) at an applied current of 100 mA. A pure Ar gas stream was used as the purge gas before the electrolysis and the carrier gas in the total electrolysis process
