A major advantage of this method is the fact that the cation stoi-chiometry of the ceramic target is well reproduced in the deposited film [1,3,4]. This makes the method useful for the preparation of thin electrolytes in anode supported cells.

Ajith Kumar, P. Kuppusami. We have investigated the deposition of 91% ZrO2 − 9% Y2O3 thin films by a variety of sputtering techniques for the application as electrolytes in thin film solid oxide fuel cells. The chapter describes modern nanomaterials and designs for solid oxide fuel cells (SOFCs), including cathode, anode, interconnect and electrolyte materials.

The chapter then discusses the trend towards miniaturization and lowering of the operating temperatures of SOFCs. It then describes new advances and tools for rational SOFC material design.

Cathode. The cathode is the SOFC electrode where electrochemical reduction of oxygen occurs. For this, the cathode must have: (1) adequate porosity (approximately %) to allow oxygen diffusion; (2) chemical compatibility with the other contacting components (usually the electrolyte and interconnect) under operating conditions; (3) a thermal expansion coefficient.
