What is Mechanical Properties of Micro-tubular Solid Oxide Fuel Cell Anodes about?
A fundamental issue with micro-tubular solid oxide fuel cells (SOFCs) is improvement of the mechanical strength of the cell. Fabricated using extrusion and co-firing techniques, the approximately 1.7 mm diameter SOFC tubes examined in this work are composed of a 50:50 NiO and Gd 0.2 Ce 0.8 O 2-x Gd-doped ceria (GDC) cermet anode (support tube), GDC as an electrolyte and La 0.8 Sr 0.2 Co 0.6 Fe 0.4 O 3 (LSCF)-GDC as a cathode. The mechanical properties of SOFCs are analyzed through internal burst testing and microand nano-indentation testing; the burst test is an especially important parameter because of improved power efficiency at increased fuel pressures. Results from micro-and nano-indentation tests performed on electrolyte-coated Ni-GDC anode pellets indicate that the hardness of GDC is comparable or greater than that of YSZ. In order to develop a trend for the mechanical behavior of micro-tubes in relation to variations in fabrication techniques, several parameters were varied. The standard anodes, used as a baseline, have four key design parameters as follows: they are not reduced, contain 40 vol% pore former, are sintered at 1400 • C and have a wall thickness of approximatel
