abstract = {The roll coating technique represents a novel method for
applying functional layers to solid oxide fuel cells
(SOFCs). This fast process is already used for mass
production in other branches of industry and offers a high
degree of automation. It was utilized for coating specially
developed anode (NiO + 8YSZ, 8YSZ: 8 $mol\%$
yttria-stabilized zirconia) and electrolyte (8YSZ)
suspensions on green and pre-sintered tape-cast anode
supports (NiO + 8YSZ). The layers formed were co-fired in a
single step at 1400 degrees C for 5 h. As a result, the
electrolyte exhibited a thickness of 14-18 mu m and
sufficient gas tightness. Complete cells with a
screen-printed and sintered La0.65Sr0.3MnO3-delta (LSM)/8YSZ
cathode yielded a current density of 0.9-1.1 A cm(-2) at 800
degrees C and 0.7 V. which is lower than the performance of
non-co-fired slip-cast or screen-printed Julich standard
cells with thinner anode and electrolyte layers. The
contribution of the cell components to the total
area-specific resistance (ASR) was calculated by analyzing
the distribution function of the relaxation times (DRTs) of
measured electrochemical impedance spectra (EIS) and
indicates the potential improvement in the cell performance
achievable by reducing the thickness of the roll-coated
layers. The results show that the anode-supported planar
half-cells can be fabricated cost-effectively by combining
roll coating with subsequent co-firing. (C) 2011 Elsevier
