Fuel cells can be applied as highly efficient auxiliary power units when being supplied with hydrogen. Since there is no adequate hydrogen infrastructure available yet, liquid fuels like Diesel can serve as a hydrogen source when it is converted into a hydrogen-rich gas in a reforming process fuel conversion by steam reforming (SR) promises the highest hydrogen yield in comparison to autothermal reforming (ATR) or catalytic partial oxidation (CPO). In the presented work several SR catalysts were tested at 750 °C and a steam to carbon ratio of 4, using a Diesel reference fuel with a sulphur content of ζ_(s)<10 ppm. Steam reforming was studied for varying Gas Hourly Space Velocities (GHSV) with respect to the hydrogen yield. In addition, studies of catalyst deactivation in the presence of sulphur and the catalysts' ability to regenerate by carbon combustion with air were completed. Some catalysts show promising results, while we identify one catalyst that has a high potential for a continuous Diesel SR application. Closing the presentation, we discuss the reproducibility of the results, and we give recommendations for further investigations.
