AB  - Intermediate temperature solid oxide fuel cells (IT-SOFCs) were fabricated depositing proton conducting BaCe0.9Y0.1O3-x (BCY10) thick films on cermet substrates made of nickel oxide-yttrium doped barium cerate (NiO-BCY10) using electrophoretic deposition (EPD) technique. The influence of the EPD parameters on the microstructure and electrical properties of BCY10 thick films was investigated. Deposited BCY10 thick films together with green anode substrates were co-sintered in a single heating treatment at 1,550 degrees C for 2 h to obtain dense electrolyte and suitably porous anodes. The half-cells were characterised by field emission scanning electron microscopy (FE-SEM) and by X-ray diffraction (XRD) analysis. A composite cathode specifically developed for BCY electrolytes, made of La0.8Sr0.2Co0.8Fe0.2O3(LSCF, mixed oxygen-ion/electronic conductor) and BaCe0.9Yb0.1O3-delta (10YbBC, mixed protonic/electronic conductor), was used. Fuel cells were prepared by slurry coating the composite cathode on the co-sintered half-cells. Fuel cell tests and electrochemical impedance spectroscopy (EIS) were performed in the 550-700 degrees C temperature range. A maximum power density of 296 mW cm(-2) was achieved at 700 degrees C for electrolyte deposited at 60 V for 1 min.

AB  - Nano-sized BaCe0.9Y0.1O3 - delta (BCY10) protonic conductor powders were used to prepare Ni-BCY10 cermets for anode-supported intermediate temperature solid oxide fuel cells. A new wet-chemical route was developed starting from Ni nitrates as precursors for NiO. BCY10 powders were Suspended in a Ni nitrate aqueous Solution that was evaporated to allow NiO precipitation on the BCY grains, obtaining NiO-BCY10 cermets. To obtain the final Ni-BCY10 anodes, pellets were reduced in dry H-2 at 700 degrees C. The structural and microstructural properties of the pellets were investigated using X-ray diffraction analysis and field emission scanning electron microscopy. A homogeneous dispersion of perovskite and nickel phases was observed. The chemical stability of the anodes was evaluated under wet H-2 and CO2 atmosphere at 700 degrees C. The electrical properties of the Ni-BCY10 pellets were evaluated using electrochemical impedance spectroscopy measurements. The Ni-BCY10 cermet electrodes showed large electronic conductivity, demonstrating percolation through the Ni particles, and low area specific resistance at the BCY10 interface. These characteristics make the cermet suitable for application in BCY-based protonic fuel cells. The developed chemical route offers a simple and low-cost procedure to obtain promising high performance anodes.

AB  - Proton conducting BaCe0.9Y0.1O3-x (BCY10) thick films are deposited on cermet anodes made of nickel-yttrium doped barium cerate using electrophoretic deposition (EPD) technique. BCY10 powders are prepared by the citrate-nitrate auto-combustion method and the cermet anodes are prepared by the evaporation and decomposition solution and suspension method. The EPD parameters are optimized and the deposition time is varied between I and 5 min to obtain films with different thicknesses. The anode substrates and electrolyte films are co-sintered at 1550 degrees C for 2 h to obtain a dense electrolyte film keeping a suitable porosity in the anode, with a single heating treatment. The samples are characterized by Held emission scanning electron microscopy (FE-SEM) and energy dispersion spectroscopy (EDS). A prototype fuel cell is prepared depositing a composite La0.8Sr0.2Co0.8 Fe0.2O3 (LSCF)-BaCe0.9Yb0.1O3-delta (10YbBC) cathode oil the co-sintered half cell. Fuel cell tests that are performed at 650 C oil the prototype single cells show a maximum power density of 174 mW cm(-2).
