AbstractA single step co-firing process for fabricating solid oxide fuel cells (SOFCs) requires refractory electrodes to prevent excessive sintering of the electrode while facilitating full-density sintering of the electrolyte. Single cell current-potential curves and impedance measurements indicate that the majority of the performance losses occur in the cathode and are due to activation polarization. A-site deficient calcium and cerium doped lanthanum ferrite cathode powders were synthesized and investigated as possible refractory cathode materials with low activation polarization losses. Four-probe conductivity measurements indicated that all compositions were suitable as cathodes. However, reactivity with YSZ reduced the conductivity by as much as two orders of magnitude, too low for use as a cathode. These refractory cathode compositions could be effective if a suitable barrier layer is applied to prevent reaction with YSZ. Experiments will investigate the applicability of a doped-ceria barrier layer to prevent reaction between the lanthanum ferrite cathode layer and the YSZ electrolyte layer.

Fuel Cell Performance

Solid oxide fuel cells (SOFCs) have been considered as a promising electricity-generation technology because of the relatively high efficiency in the conversion of chemical energy to electrical power. The cathode performance of solid oxide fuel cells (SOFC) depends substantially on its surface area, porosity and microstructure, and therefore the processing method used is very important in determining cathode performance. By optimizing the structural characteristic of the layer, the cathode performance during fuel cell performance can be fully maximized. Polyether ether ketone (PEEK) pore former was introduced in the processing method of cathode layer. The cathode layer was brush painted and sintered at 1200°C for 5 hours. TGA analysis is used to specify the sintering curve for the cathode layer. In addition, three point bending test is used to investigate the change in bending force with the addition of pore former. Characterization via FESEM allows inspection over the induced pore geometry and distribution along the layer. The study can produce a comprehensive structural analysis on the pore former addition in the precursor solution of the cathode layer for SOFC application.
