abstract = {One of the main targets in the development of
anode-supported solid oxide fuel cell (SOFCs) is to improve
the electrochemical performance. This can be achieved by
optimizing processing and microstructural parameters of the
SOFCs. Variations of the thickness of the cathode functional
layer and the cathode current collector layer the grain size
of the powders used for applying these layers, and the
sintering temperature, can influence the electrochemical
performance as such that lower operation temperatures become
possible without detrimentally affecting the power output to
a great extent. In this study the effect of variations of
the sintering temperature of the cathode on (1) the
microstructure, (2) the gas diffusivity and permeability in
the cathode, and (3) electrochemical performance of FZJ-type
anode-supported single cells, was investigated. The
FZ-Julich cell design is based on anode-supported type
cells, which are characterized by a relatively thick anode
(thickness: 1.0-1.5 mm) consisting of a NiO/8YSZ cermet, a
thin 8YSZ electrolyte, and a bi-layered cathode. The cathode
distinguished two separated layers: first a cathode
functional layer consisting of La0.65Sr0.3MnO3
(LSM)/Y2O3-stabilized ZrO2 (8YSZ) and a cathode current
collector layer of pure La0.65Sr0.3MnO3 (LSM). This study
can be considered as a follow-up of that (Journal of Power
Sources 141 (2005) 216-226) describing the improvement of
the cell performance by a systematic variation of the
microstructure. The experiments described in this paper and
the corresponding results are part of a more extensive study
to investigate in more detail the effect of the sintering
temperature on the electrochemical performance of LSM-type
SOFCs. Since research is still going on, conclusions, drawn
in this contribution, are yet not definitive.},
