J. Fuel Cell Sci. Technol 12(3), 031005 (Jun 01, 2015) (6 pages) Paper No: FC-14-1050; doi: 10.1115/1.4029875 History: Received April 22, 2014; Revised December 15, 2014; Online March 10, 2015

Microtubular anode-supported solid oxide fuel cells (μt-SOFC) were created with a metallic coil embedded in the anode to act as current collector. The electrochemical performance was experimentally examined by comparing the power density (PD) of μt-SOFC with embedded coils of different turns per unit length and composition (nickel and palladium). It is shown that an increase in the turns per unit length results in a proportional current density increase and in a quadratic increment of PD. Additional performance improvement is found for the cell with palladium current collector due to the higher catalytic activity for hydrogen oxidation.
