Abstract
A pre-reforming unit is needed if liquid hydrocarbon fuels, such as
gasoline or diesel, are used in solid oxide fuel cell (SOFC) systems. Although
pre-reforming removes most of the higher hydrocarbons, there may still be
some fractions left in the reformate flow. Ethene was chosen to be the subject
of this work because it has been analyzed to be the most significant impurity
in diesel reformate. In this work, an anode supported unit cell was used to
examine the behavior and performance of a SOFC when ethene was added to
hydrogen feed. The ethene concentration in the feed was increased stepwise
from 0 ppm to 1000 ppm and the current was kept constant for 100 hours at each
concentration level. Changes in the cell performance were monitored by
impedance spectroscopy and polarization measurements. It was detected that
ethene does not accelerate cell degradation.
