lectrochemical properties of segmented-in-series SOFC using Ni-Fe/YSZ core-shell anode |
| 초록 |
The Ni-Fe/YSZ core-shell structured anode for uniform microstructure and catalytic activity have been synthesized. A flat tubular segmented-in-series solid oxide fuel cell-stacks were prepared by decalcomania method using synthesized anode powder. The Ni-Fe/YSZ core-shell anode exhibited better electrical conductivity than a commercially available Ni-YSZ cermet anode. Also power output increased by 1.3 times with a higher open circuit voltage. The results attributed to the uniformly distributed Ni particles in the YSZ framework. The impedance spectra of a Ni-Fe/YSZ core-shell anode showed comparable reduced ohmic resistance compared with those of the commercially available Ni-YSZ cermet anode. |
