摘要

质子交换膜水电解（PEMWE）具有对电力波动的适应性，可以与光伏和风能等可再生能源相结合。为了提高316L不锈钢（316L SS）在高酸性和波动电位环境中的耐蚀性和导电性，采用多弧离子镀法制备Nb:Ti:N涂层对其进行改性。Nb:Ti:N涂层的初始界面接触电阻（ICR）为4.86 mΩ·cm²，由导电TiN、Nb₂N、NbN和Ti相组成，使316L SS的稳定电位提高到1.8 VAg/AgCl。经过4 h的极化测试，ICR达到最大值7.93 mΩ·cm²，满足美国能源部的目标（<10 mΩ·cm²）。1.2和1.8 VAg/AgCl之间的方波/三角波电位已被用于模拟波动的能量输入。结果表明，Nb:Ti:N涂层对电位波动响应迅速，特别是在三角形波形下，没有出现严重的失效现象。因此，Nb:Ti:N涂层为设计抗波动电位双极板提供了可行的参考。

Optimized corrosion resistance and electrical conductivity of Nb:Ti:N-coated 316L stainless steel under fluctuating potentials for proton exchange membrane water electrolysis

Proton exchange membrane water electrolysis (PEMWE) demonstrates adaptability to power fluctuations, enabling integration with renewable energy sources like photovoltaic and wind power. To improve the corrosion resistance and electrical conductivity of 316L stainless steel (316L SS) in high acidity and fluctuating potential environments, it has been modified with Nb:Ti:N coatings prepared by multi-arc ion plating. The Nb:Ti:N coating with initial interfacial contact resistance (ICR) of 4.86 mΩ·cm², consisting of conductive TiN, Nb₂N, NbN, and Ti phases, has increased the stable potential of 316L SS to 1.8 V_Ag/AgCl. After 4 h of polarization test, the ICR reached a maximum value of 7.93 mΩ·cm², satisfying the United States department of energy target (<10 mΩ·cm²). Square/triangular wave potentials between 1.2 and 1.8 V_Ag/AgCl have been applied to simulate fluctuating energy inputs. The results indicate that the Nb:Ti:N coating responds rapidly to potential fluctuations, particularly under triangular waveforms, without severe failure phenomenon. Thus, the Nb:Ti:N coating offers a viable reference for designing bipolar plates resistant to fluctuating potentials.
