abstract = {The operation of fuel cell systems using liquid fuels
widens the application possibilities of this promising
energy conversion technology. However, systems utilizing
diesel and jet fuel reforming are fairly complex and suffer
from poor stability and limited dynamics. To address these
challenges, this paper investigates the steady-state and
transient operation of a 28 kWth fuel processor on the
systems level. With the help of experiments that make use of
the developed prototype, suitable operating parameters are
sought to maximize the simultaneous fuel conversion in the
reformer and CO conversion in the shift reactor.
Furthermore, a load change strategy is developed with the
aim of keeping the CO concentration at the fuel cell anode
inlet below the target concentration of $1\%$ of the wet
product gas at all times. The identified parameters enable
very high conversions $(>99.95\%)$ and CO concentrations
even lower than the target during steady-state operation
using three commercial fuels under full load. The developed
load change strategy was validated during 90 min tests,
including 16 load change cycles with loads between $40\%$
and $100\%.$ As well as providing excess steam during load
change, the selection and control of optimal O2/C and H2O/C
ratios and temperature levels proved to be of key
importance. In order to minimize the CO concentration, it is
recommended to operate the reformer at the identified
parameters for each fuel and keep the shift outlet
temperature between 295 and 300 °C by adjusting the water
feed. The proposed fuel processor concept and the
experimentally-validated operating strategies in this work
can enable the successful implementation of fuel cell
technology in different application areas, including
auxiliary power units, remote power systems and range
extenders.},
