Laser machining of LaNi0.6M0.4O3−δ (M: Co, Fe) dip-coated on a Fe-22Cr mesh material to obtain a new contact coating for SOFC
Abstract
A Fe–22Cr mesh was dipped into a ceramic (LaNi<sub>0.6</sub>M<sub>0.4</sub>O<sub>3−δ</sub>; M: Co, Fe) slurry to form a metallic/ceramic material as contact coating for solid oxide fuel cells (SOFCs). This composite was directly adhered to a Crofer22APU channeled interconnect and micro-holes were performed on coating using a femtosecond laser. Then, La<sub>0.6</sub>Sr<sub>0.4</sub>FeO<sub>3</sub> (LSF) cathode was spray deposited on top of this ablated system to analyze the formed structures in terms of the electrical performance, processing reproducibility and long-term behavior at 800 °C. The adequate reproducibility of the process was confirmed through area specific resistance (ASR) testing on four replicas for each system. After long-term treatment, the chromium diffusion within both the interconnect and mesh of the composite was quantitatively analyzed using energy dispersive X-ray spectroscopy (EDX). The laser irradiated composite showed short-range damage, which was limited to the formation of iron and chromium oxides due to the evaporation and oxidation of the mesh.
