Abstract
To asses the reliability of solid oxide fuel cell (SOFC)
stacks during operation, the stress field in the stack must be
known. During operation the stress field will depend on time as
creep processes relax stresses. This work reports further details on
a newly discovered creep phenomenon, accelerated creep, taking
place during the reduction of the anode. This relaxes stresses at a
much higher rate (~×104) than creep during operation. The
phenomenon has previously been studied by simultaneous loading
and reduction. With the recorded high creep rates, the stresses at
the time of reduction should reduce significantly over minutes. In
this work the stresses are measured in-situ before and after the
reduction by use of XRD. The phenomenon of accelerated creep
has to be considered both in the production of stacks and in the
analysis of the stress field in a stack based on anode supported
SOFCs.
