Fabrication and characterization of anode-supported micro-tubular solid oxide fuel cell based on BaZr0.1Ce0.7Y0.1Yb0.1O3−δ electrolyte

Abstract Anode-supported micro-tubular solid oxide fuel cells (SOFCs) based on a proton and oxide ion mixed conductor electrolyte, BaZr0.1Ce0.7Y0.1Yb0.1O3−δ (BZCYYb), have been fabricated using phase inversion and dip-coating techniques with a co-firing process. The single cell is composed of NiO–BZCYYb anode, BZCYYb electrolyte and La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)–BZCYYb cathode. Maximum power densities of 0.08, 0.15, and 0.26 W cm−2 have been obtained at 500, 550 and 600 °C, respectively, using H2 as fuel and ambient air as oxidant.
