abstract = {Solid oxide protonic fuel cells are one of the most
efficient means of directly converting stored chemical
energy to usable electrical energy. Acceptor-doped Ba(Zr,
Ce)O3 perovskite-type oxides are the preferred electrolyte
choice as they provide higher conductivity due to lower
activation energy. While substantial progress has been made
on small-sized protonic laboratory-scale cells, a
considerable challenge has been upscaling robust planar-type
devices. This paper employs a cost-effective inverse tape
casting route and screen printing to fabricate flat planar
anode-supported protonic fuel cells consisting of
NiO-SrZr0.5Ce0.4Y0.1O3-δ substrate, SrZr0.5Ce0.4Y0.1O3-δ
electrolyte, and BaCo0.4Fe0.4Zr0.1Y 0.1O3-δ as the cathode.
The processing parameters were analyzed and adjusted to
obtain defect-free single cells of dimension up to 100 mm ×
100 mm × 0.5 mm with diminished warping. In addition, the
smooth tri-layered green tapes yielded suitably dense and
gas-tight electrolyte layers after co-sintering at 1300
°C/5 h. Finally, the electrochemical performance of the 50
× 50 mm2 SrZr0.5Ce0.4Y0.1O2.95 based cells was evaluated,
and their impedance spectra were deconvoluted to identify
all performance-related polarization processes via the
distribution of relaxation time.},
