Abstract: A process for operating an electrolysis apparatus for splitting water at both high and low ambient temperatures includes providing at least one electrolysis unit including at least one electrolytic cell and having at least one inlet opening for a first reactant stream and at least one outlet opening for a first product stream, producing the first product stream from the first reactant stream in the electrolysis unit, separating the product stream into water and gas streams, and cooling the water stream in at least one obliquely-oriented cooling apparatus dissipating the heat of the water stream directly to the environment. The cooling of the water stream is interrupted if the electrolysis unit is shutdown or the electrolysis unit is in standby operation. The ambient temperature is detected and, if the ambient temperature is below 1°, the water stream is emptied from the cooling apparatus into a liquid storage device.
