abstract = {With their high electrochemical efficiency, solid oxide
fuel cells (SOFCs) and solid oxide electrolyzers (SOEs)
offer viable means of reducing energy sector greenhouse gas
emissions and storing surplus renewably-generated power. At
present, these systems have operating temperatures of over
600 °C. During start-up, following cooling or in an
emergency shut-off situation, a premixed safety gas is
necessary which prevents damage to the cell's anode
substrate. To date, safety gas has been industrially
produced and stored in compressed gas cylinders. Given an
SOFC system's size, these cylinders must be transported and
stored in close proximity and replaced following gas
expenditure. The storage space required, as well as the
continuous replacement of gas cylinders, increases system
size and costs. This paper presents a solution to this
problem in the form of a specially developed safety gas
generator that generates an on-demand synthetic safety gas
via the system's infrastructure. The functionality of this
component is experimentally validated in tests conducted
with a 4-cell stack.},
