In this study, the performances of single micro-tubular solid oxide fuel cells based on the NiO-YSZ/YSZ/LSM system with two different current-collection architectures were compared. In the first case, a straight Ni wire was inserted within the hole of the cell before the electrochemical testing, and in the second case, a coil integrated-current collector within the anode layer was already arranged for electrical connections during cell processing. The current produced in each case was collected from double terminal and the performance of the cells was estimated by electrochemical I-V characterization. The maximum power outputs generated in the cells with the integrated-current collector and the common current-collection architectures were of ∼200 and ∼55 mW cm-2, respectively at 800 °C under a wet H2 fuel flow.

Abstract
In this study, the performances of single micro-tubular solid oxide fuel cells based on the NiO-YSZ/YSZ/LSM system with two different current-collection architectures were compared. In the first case, a straight Ni wire was inserted within the hole of the cell before the electrochemical testing, and in the second case, a coil integrated-current collector within the anode layer was already arranged for electrical connections during cell processing. The current produced in each case was collected from double terminal and the performance of the cells was estimated by electrochemical I-V characterization. The maximum power outputs generated in the cells with the integrated-current collector and the common current-collection architectures were of ∼200 and ∼55 mW cm-2, respectively at 800 °C under a wet H2 fuel flow.
