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