摘要
为了提高质子交换膜燃料电池双极板的耐久性，对混合层和交替层（混合c /Cr和替代c /Cr）两种涂层进行了比较评价。混合- c /Cr和alt-C/Cr的i0.84 V分别降至0.10和0.27 μA·cm−2，界面接触电阻分别为1.14和1.01 mΩ·cm2，满足DOE目标。分析表明，交替层防止了C层的分层，有利于形成多个界面，从而改善了界面电位分布。本研究的结果证实了混合层和交替层涂层策略在双极板上高性能涂层的前景。
Comparative study of mixed- and alternating-layer C/Cr coated metal bipolar plates under high potentials toward proton exchange membrane fuel cells
To improve the durability of bipolar plates in proton exchange membrane fuel cells, two types of coatings with mixed- and alternating-layers (mix-C/Cr and alt-C/Cr) are comparatively evaluated. Both coating designing strategies meet DOE targets with i0.84 V declining to 0.10 and 0.27 μA·cm−2 and achieving low interfacial contact resistance of 1.14 and 1.01 mΩ·cm2 for mix-C/Cr and alt-C/Cr, respectively. Analysis suggests that alternating-layer prevent the delamination of C layer and contributes to multiple interfaces which polishing the interfacial potential distribution. The results of this study confirm the promise of mixed- and alternating-layer coating strategies for high-performance coatings on bipolar plates.
