A system for regulating the temperature and pressure of a high temperature electrolyzer (SOEC) operating irreversibly as a fuel cell stack (SOFC)

摘要

The present invention relates to a system that can operate reversibly as a SOFC fuel cell stack or as a SOEC electrolyzer. According to the present invention, a bypass line or a bypass path is used to bypass a part of the hot gas generated from a chamber called an oxygen chamber (SOEC mode anode chamber, SOFC stack mode cathode chamber) as required. Which cools the heat exchanger provided in the path through which oxygen flows.
