abstract = {Solid oxide fuel cells (SOFCs) directly convert the
chemical energy of fuels into electrical energy with high
efficiency. Under certain conditions oxygen can diffuse to
the Ni/8 $mol\%$ Y2O3-doped ZrO2 substrate of
anode-supported SOFCs, then the nickel re-oxidizes, leading
to cracks in the electrolyte and cell failure thus limiting
the durability of SOFCs. In order to improve the stability
of SOFCs with respect to oxidation, the inner surface of the
porous substrate is coated with a ZrO2 oxidation resistance
layer using atomic layer deposition (ALD) with the
precursors tetrakis(ethylmethylamino)zirconium (TEMAZ) and
molecular oxygen. This TEMAZ/O2–ZrO2 ALD process has not
yet been reported in the literature and hence, the
development of the process is described in this paper. The
inner surface of the porous substrate is coated with ZrO2
and the film thickness is compared with theoretical
predictions, verifying the ALD model. Furthermore, the
coating depth can be estimated using a simple analytical
equation. The ALD ZrO2 film protects the nickel in the
substrate against oxidation for at least 17
re-oxidation/re-reduction cycles. The ZrO2 inner surface
coating is a highly promising candidate for enhancing the
resistance of SOFCs to re-oxidation because of the excellent
oxidation resistance and good cycling stability of the
film.},
