HT-PEFC Systems Operating with Diesel and Kerosene for APU Application

HT-PEFC systems designed for operation with diesel and kerosene are currently being developed in Jülich. Fuel processing reactors consisting of an autothermal reformer, a two-stage water-gas shift reactor and a catalytic burner were designed with the aim of maximizing heat integration and minimizing system volume. The stack is designed for operation with reformate coming from fuel processing.This paper highlights the system architecture as well as experimental results in the 5 kWel power class. The integrated system concept was characterized via sub-system experiments. The stack performance was tested under system-relevant conditions. Finally, actual system performance was compared with APU targets.
