A simulated interconnect/contact/cathode/cathode support test cell is fabricated to investigate the effectiveness of the high-entropy alloy as the contact material on the microstructure and the performance of the converted spinel-based layer. Although the CuMnNiFeCo alloy powder is selected as the contact precursor, it showed good sinterability after sintering at 900°C for 2 h in air. The electrical performance of the contact layer is evaluated by the area-specific resistance measurement, including isothermal exposure and thermal cycling. The compatibility of the contact layer with adjacent components is investigated through observing the cross-sectional view of the test cell. Furthermore, the effectiveness of the contact layer in inhibiting Cr migration is also assessed.

用于 SOFC 阴极侧接触应用的高熵合金尖晶石基层的研究

制造了模拟互连/接触/阴极/阴极支撑测试单元，以研究高熵合金作为接触材料对转化的尖晶石基层的微观结构和性能的有效性。虽然选择CuMnNiFeCo合金粉末作为接触前驱体，但在空气中900℃烧结2小时后表现出良好的烧结性能。接触层的电气性能通过特定面积电阻测量进行评估，包括等温暴露和热循环。通过观察测试电池的横截面图来研究接触层与相邻部件的兼容性。此外，还评估了接触层抑制 Cr 迁移的有效性。
