Heat exchanger for fuel cell system and method for operating fuel cell system

The invention relates to a heat exchanger (1) for a fuel cell system (100), in particular an SOFC system operated by means of a liquid fuel, having a plurality of heat exchange elements (2), wherein thermal energy can be transferred by the heat exchanger (1) between a system exhaust gas line (3) and an anode feed line (4) of a fuel cell system (100), having an evaporation region (5), an overheating region (6) and a reformation region (7), which are fluidically connected to each other, wherein the heat exchange elements (2) comprise a catalytic material at least in part. The invention further relates to a use of the heat exchanger (1) and to the fuel cell system (100) having the heat exchanger (1). The invention further relates to a method for operating the fuel cell system (100), in particular a SOFC system having the heat exchanger (1). 本发明涉及一种用于燃料电池系统(100)、特别是以液体燃料运行的SOFC系统的换热器(1)，其具有多个传热元件(2)，其中，在燃料电池系统(100)的系统废气管线(3)和阳极供应管线(4)之间能够通过换热器(1)传递热能，它包括彼此流体连通的蒸发区域(5)、过热区域(6)和重整区域(7)，其中，所述传热元件(2)至少部分包含催化材料。本发明还涉及
