Abstract
This invention relates to an electrochemical system (1) suitable for hot standby, comprising: at least one electrochemical module (11) including a fuel electrode, an oxidant electrode, and a membrane; at least one fluid inlet line (10) leading to the electrochemical module (11), particularly to the fuel electrode; at least one fluid outlet line (12) exiting the electrochemical module (11); and a gas recirculation unit (15) for recirculating gas or gas mixtures exiting the electrochemical module (11) back to the fuel electrode. The system includes an inert gas unit (3), preferably a nitrogen unit, for supplying inert gas to the at least one fluid inlet line (10). The invention also relates to a method for electrolysis in hot standby mode.
