摘要:
The invention relates to an improvement in the process of electrolyzing water at high temperatures implemented by a cell stack reactor. According to the invention, the following steps are carried out: a/ simultaneously circulating the water vapor (12, 13) to each cathode and to each anode as a leaching gas, the temperatures of the water vapor at the inlet of each anode and each cathode being lower than the high temperatures at which the electrolysis is carried out and the water vapor circulating at the anode being at an overpressure with respect to the cathode, b/ upon starting the electrolysis, supplying electrical power having a substantially constant electrical voltage U0 across the terminals of the stack and maintaining same. Thus, in the event of breakage of one or more cells, the complete destruction of the stack is avoided and high production efficiency is maintained. In addition, the invention provides for maintaining efficiency during aging.
