Abstract (en)

The control unit comprises a temperature probe (10), which is adapted to detect a temperature at a place of a conduit, first conditioning unit (20) for physical conditioning of the fluid connected to the conduit with respect to a high temperature electrolyzer (5), and a first return conduit, which is adapted to recycle of fluid leaked from the electrolyzer to a location of the conduit, which is located in upstream in relation to the high temperature electrolyzer. The control unit controls the first conditioning unit as a function of the detected temperature by the temperature probe. The control unit comprises a temperature probe (10), which is adapted to detect a temperature at a place of a conduit, and first conditioning unit (20) for physical conditioning of the fluid connected to the conduit with respect to a high temperature electrolyzer (5), and a first return conduit, which is adapted to recycle of fluid leaked from the electrolyzer to a location of the conduit, which is located in upstream in relation to the high temperature electrolyzer. The control unit controls the first conditioning unit as a function of the detected temperature by the temperature probe. The return conduit consisting of leaked fluid leaked from the electrolyzer is connected to a heat exchanger (35) connected to the conduit, and opens into the conduit. The fluid located in the conduit is conditioned by recycled fluid, both before supplying to the high temperature electrolyzer. The control unit further comprises a second conditioning unit designed as a flow generator, and a second return conduit (21). The control unit controls conditioning unit as a function of the temperature detected by the temperature probe. A first temperature probe is provided on the conduit at a first location in upstream of the high temperature electrolyzer, and a different second temperature probe is provided in the line at a second location in downstream of the high temperature electrolyzer. The first conditioning unit is constructed as a heater, which is adapted to heat the fluid or as a flow generator that is adapted to pressurize fluid located that in the conduit. The second return conduit returns the fluid from the high temperature electrolyzer to a location of the conduit, which is arranged in upstream of the high temperature electrolyzer, is connected to the heat exchanger, and is adapted to thermally condition the fluid before supplying to the high temperature electrolyzer. The heat exchanger in relation to the first conditioning unit is connected to in upstream of the conduit.
