Description
技术领域
本发明属于质子交换膜燃料电池领域，具体涉及一种用于质子交换膜燃料电池金属双极板的改性，具体为Nb/NbN/(Nb,Ta)2AlC多层梯度涂层及其制备方法。
背景技术
质子交换膜燃料电池具有结构紧凑、体积小、能量密度高、效率高、启动快、低温运行以及零排放的优势，被认为是现阶段理想的清洁发电能源。双极板作为PEMFC最重要的组成部件之一，将单电池串联、并联或是混合联结形成电池堆，起到支撑的作用，还能够隔绝阴极、阳极的反应气体，排出电池堆反应产生的热量和水，对PEMFC电池堆的性能至关重要。目前双极板主要有石墨双极板、金属双极板和复合双极板三种。金属双极板强度高，易加工，超薄双极板容易获得规模化生产，能提升燃料电池的比功率。但是双极板工作环境中具有多种腐蚀性离子，如SO4 2-、F-等，金属双极板材料容易受到腐蚀，形成钝化层，增加双极板与扩散层之间的接触电阻增大，极大影响燃料电池电堆的输出功率与耐久性。因此通过表面涂层改性，降低金属双极板表面接触电阻、提高其导电性和耐腐蚀性是其商业化应用的关键。目前的双极板涂层主要有碳基涂层、贵金属涂层，导电高分子聚合物涂层、疏水涂层、过渡金属陶瓷化合物等。碳基涂层具有优异的耐腐蚀性能，并且导电性、导热性能优良，同时还具有较低的生产成本，已经得到了广泛的研究。但是碳类涂层沉积效率较低，影响其大规模化应用。贵金属涂层具有优异的耐腐蚀性和导电性，但是成本太高。导电高分子聚合物涂层可以对双极板起到很好的防护作用，具有良好的耐腐蚀性和导电性，其中研究较多的就是聚苯胺(PANI)和聚吡咯(PPy)，但是涂层与基体的结合力较弱。疏水涂层的疏水性能可以在很大程度上影响双极板的腐蚀速率，但难以保持长久的稳定性。过渡金属陶瓷化合物有极好的物理、化学和力学性能，在双极板工作环境中有优异的耐腐蚀性和稳定性，并且还能保持高导电性，是PEMFC双极板理想的涂层材料之一，有良好的发展前景。但是，目前的过渡金属陶瓷化合物涂层普遍存在制备成本高，效率低，涂层中存在针孔、大颗粒，或柱状晶，严重影响其长期稳定性，涂层结合力差或者长期稳定性差导致的脱落问题会对电堆产生恶劣的影响，加速电堆的老化进程。
发明内容
针对现有技术缺陷，本发明提供一种用于质子交换膜燃料电池金属双极板的多层梯度涂层及其制备方法，获得具有均匀、致密、附着力高的涂层，减少柱状晶、针孔和大颗粒等缺陷，有效提高金属基板的抗腐蚀能力与腐蚀后导电性能。整体涂层的制备速率快，工艺易控制，能大幅度提高双极板的性能，进而提高燃料电池的服役寿命。
为实现上述目的，本发明所采取的技术方案为：
一种用于质子交换膜燃料电池金属双极板的多层梯度涂层，包括金属基板，Nb过渡层，NbN连接层和(Nb,Ta)2AlC外层涂层。其特征在于，所属涂层的材料为Nb/NbN/(Nb,Ta)2AlC多层梯度涂层，Nb层为过渡层，能减少层间热膨胀失配度同时提高各层的元素相容性，提高涂层的结合力。
