dc.description.abstractEnThe praseodymium nickelate oxide Pr<sub>2</sub>NiO<sub>4+<i>δ</i></sub>, a mixed conducting oxide with the K<sub>2</sub>NiF<sub>4</sub>-type structure, was evaluated as cathode for low temperature solid oxide fuel cells (<i>T</i> = 873 K). The electrochemical performance of the cathode has been improved by optimization of the microstructure of the porous cathode combined with the use of a ceria barrier layer in between the cathode and zirconia electrolyte. Both low polarization and ohmic resistances were obtained using Pr<sub>2</sub>NiO<sub>4+<i>δ</i></sub>-powders with a median particle size of 0.4 μm, and sintering the screen printed layer at a sintering temperature of about 1353 K for 1 h. These manufacturing conditions resulted in a cathode microstructure with well established connections between the cathode particles and good adhesion of the cathode on the electrolyte. Full-sized anode supported cells have been manufactured using the same process conditions for the Pr<sub>2</sub>NiO<sub>4+<i>δ</i></sub> cathode and tested. The best results were obtained when using a dense Ce<sub>0.8</sub>Gd<sub>0.2</sub>O<sub>1.9</sub> (20CGO) barrier layer. While a complete optimization of the cell preparation has not yet been achieved, the electrochemical performances of anode supported cells with Pr<sub>2</sub>NiO<sub>4+<i>δ</i></sub> are higher than those with the well known state-of-the-art La<sub>0.6</sub>Sr<sub>0.4</sub>Fe<sub>0.8</sub>Co<sub>0.2</sub>O<sub>3−<i>δ</i></sub> (LSFC) material.
