Together with the high-temperature polymer electrolyte fuel cell, the reactor for the autothermal reforming (ATR) of liquid hydrocarbons, such as diesel fuel or kerosene, is the key component of the Jülich fuel cell system in the 5kW_e power class. This paper presents some of Jülich’s most recent development in the field of ATR reactors, specifically the ATR 12. ATR 12 is characterized by a new concept for the internal generation of superheated steam as one of the ATR reactants using concentric shells instead of coiled tubing and particularly by the integration of an electric heating wire to enable fast and autonomous start-up. Three different experimental procedures for heating up the ATR 12 are presented and discussed, the most suitable of which enables the start-up of the ATR 12 within approximately 15min. As a consequence, from the system perspective, the bulky start-up burner, which is also difficult to control, along with the corresponding heat exchanger unit, can be dispensed with. Additionally, comprehensive steady-state experiments identify suitable reaction conditions for the operation of the ATR 12.

自热重整器设计的进展

与高温聚合物电解质燃料电池一起，用于液态碳氢化合物（例如柴油或煤油）的自热重整（ATR）的反应堆是5kW _e燃料电池中Jülich燃料电池系统的关键部件功率等级。本文介绍了Jülich在ATR反应堆领域的最新进展，特别是ATR12。ATR12的特点是内部产生了过热蒸汽的新概念，它是使用同心壳而不是连续油管的ATR反应物之一。特别是通过集成电加热丝来实现快速，自主的启动。提出并讨论了三种不同的加热ATR 12的实验程序，最适合的一种是在大约15分钟内启动ATR 12。结果，从系统的角度来看，可以省去也难以控制的笨重的启动燃烧器以及相应的热交换器单元。此外，
