A fabrication method for the preparation of Ni/3 mol% Y2O3-ZrO2 (Ni/TZ3Y) cermet electrodes from various commercial powders has been described. The fabrication parameters investigated include: particle size and particle size distribution of NiO and TZ3Y powders, Ni content in the cermet, firing temperature, electrode thickness and the effect of adding pore-formers. Ni/TZ3Y cermet anodes were prepared by screen printing and the electrode performance was characterised by galvanostatic current interruption and electrochemical impedance spectroscopy techniques. The results showed that the electrochemical activity of Ni/TZ3Y cermet anodes for hydrogen oxidation is strongly dependent on the selection of fabrication parameters, and the effect of these processing parameters on the electrode microstructure is closely interlinked. The most critical parameters appear to be the particle size and particle size distribution of NiO and TZ3Y powders, which can be controlled by screening various commercial powders and by optimising the heat treatment conditions of these powders. For the best anode, the overpotential losses at 800 degrees C were less than 90 mV at a current density of 350 mA cm(-2). The anode degradation, performed on 50 mm x 50 mm x 100 mu m TZ3Y electrolyte cells, was less than 1.7% over the similar to 4300 h test period under a current load of 250 mA cm(-)2 at 900 degrees C.
