Abstract

Commercialization of solid oxide fuel cell is feasible with hermetic sealing, low sintering and low operating temperature of the fuel cell. In this context, selection of Gd doped cerium oxide (GDC) and packing the cell into Low-Temperature Co-fired Ceramics (LTCC) with proper gas channels can realize the development of safe, fuel-efficient and low-temperature solid oxide fuel cells. The present study discusses the material design of solid oxide fuel cell components (anode, cathode and electrolyte) and inter compatibility of the anode, cathode and electrolyte for integration into LTCC. The shrinkage behaviour of the materials is studied using dilatometry. The shrinkage of the fuel cell components is brought closer to the LTCC by appropriate additives to the component materials. The electrochemical impedance spectroscopy is conducted to study the resistance of the modified electrolyte material. As-synthesised materials are characterized using X-ray diffractometry (XRD), scanning electron microscopy (SEM) and particle size analysis.
