abstract = {The morphology of layers of fully yttria-stabilised
zirconia (YSZ) deposited by reactive magnetron sputtering
was studied with regard to their application as thin
electrolytes for solid oxide fuel cells (SOFC). A thin layer
of YSZ was deposited on top of anode substrates for SOFC.
The substrate comprises the warm-pressed anode itself, which
supports the complete cell, and an anode functional layer
deposited by vacuum slip casting, which is in direct contact
with the electrolyte. From previous experiments it is known
that non-assisted reactive DC magnetron sputtering produces
layers with rather high leak-rate even when depositing at
high temperatures. Residual pores on the substrates'
surfaces are responsible for the incomplete coverage by the
thin electrolyte and are detrimental to the cell's
performance. In the present paper, the effect of increasing
bias power applied to the substrate is studied. A clear
improvement of the layer morphology and gas-tightness can be
observed with increasing bias power. SOFC single cell-tests
show art improved performance with regard to standard
wet-ceramic processing routes. (C) 2012 Elsevier B.V. All
