Abstract (en)

[origin: EP2495353A2] Operating oxygen consuming electrode as cathode for electrolysis of alkali chlorides or hydrochloric acid, in an electrochemical cell, comprises at least partially heating oxygen containing process gas that is supplied to electrode, using a heat source of electrolysis, preferably by heat exchange with a process stream obtained by electrolysis or with a process stream that is reprocessed subsequent to electrolysis, before contacting with the oxygen consuming electrode, to a temperature that is not > the temperature of cathode chamber in the cell or to less than 50[deg] C, preferably less than 10[deg] C.
