Spray Pyrolysis Deposition of Electrolyte and Anode for Metal Supported Solid Oxide Fuel Cell

Abstract

Metal supported solid oxide fuel cells offer many advantages including increased robustness, improved thermal shock resistance and decreased cost. However, fabricating metal- supported solid oxide fuel cells using conventional techniques are either very difficult or very costly. In this study, two processes of spray pyrolysis deposition - pneumatic spray deposition and electrostatic spray deposition were used to deposite samaria doped ceria (SDC) electrolytes on different substrates and deposite NiO-SDC anodes on porous stainless steel substrate. A cathode layer was subsquently applied on the electrolyte by stencil prining for electrochemical testing. The test results indicaed that the electrolyte had reasonable cell performance but the topography of the anode needed optimization.
