Abstract
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.
