本論文選用Fe-Cr基合金Crofer22及Zmg232為固態氧化物燃料電池(SOFC)金屬連接板材料研究材料。金屬連接板通常在長時間高溫氧化情況下，氧化層會變的太厚而使得導電性降低。因此，合金上網印La0.7Sr0.3MnO3(LSM)漿料，並經氮氣高溫燒結後可在800℃高溫操作環境下有良好的抗氧化能力。由XRD分析表面之化合物及EPMA橫截面分析可得知LSM塗層確實有效抑止Cr之氧化物的成長。由電阻量測ASR(Area Specific Resistance)可得知氧化後氧化層厚度薄的連接板具有較低的ASR電阻值，且具LSM保護之金屬連接板ASR值經長時間高溫氧化後也低於沒有受保護的金屬原材。

The chromium-based alloys, Crofer22 and Zmg232, were selected for the interconnect of solid oxide fuel cell(SOFC) in this thesis. Under a long term and high-temperature oxidation，the oxide scale of interconnect usually become too thick so that lowering the electric conductivity of interconnects. Therefore, the alloys were coated by screen printing and sintered in nitrogen atmosphere. It showed that the LSM/alloys has good oxidation-resistant. The oxidized samples examined by X-ray diffraction (XRD) and electron probe x-ray microanalyzer (EPMA) display their ability in suppressing the growth of chromina.
The results showed that the thinner oxide scale has the lower area specific resistance, and LSM coating alloys have lower ASR than the raw alloys.
