摘要

A heat management method in a high-temperature steam electrolysis [SOEC] (FIG. 1), to solid oxide fuel cells [SOFCs] (FIG. 2) and/or to a reversible high-temperature fuel cell having the SOEC and SOFC modes of operation [rSOC] (FIG. 1/2). The steam required (1) is supplied from at least one external source and at least one offgas stream (4, 12, 12a) is cooled at least once (3, 11, 18, 35) downstream of the cell [SOEC, SOFC, rSOC] (5, 5a). The internal generation of steam required (1, 38) is effected by internal recuperative heating of externally supplied water (47, 48, 51). The energy from the at least one cooling operation (3, 11, 18, 35) of the at least one offgas stream to be cooled (4, 4a, 12, 12a, 17, 20, 34, 36) is used for this purpose, and at the same time the external steam supply (1, 38) is reduced or shut down. Also a high-temperature steam electrolysis [SOEC] arrangement, solid oxide fuel cell [SOFC] arrangement and/or reversible high-temperature fuel cell arrangement with the SOEC and SOFC modes of operation [rSOC], each having an electrolysis/fuel cell (5, 5a), two gas supply conduits (8, 15), two gas outlet conduits (4, 12/12a), wherein at least one water evaporation arrangement (18, 35, 53), a steam generator and/or heat exchanger for steam generation is arranged in at least one gas outlet conduit (4, 12, 12a) in order to generate steam (1, 38) from water (47, 48, 51).
