金属双极板被认为是石墨双极板的经济有效且可行的替代品，可用于质子交换膜燃料电池的高功率密度。然而，金属双极板的寿命取决于表面涂层，耐久性评估非常昂贵和耗时。因此，建立涂层金属双极板的寿命评估方法，对涂层金属双极板的快速开发具有重要意义。在这项研究中，涂层金属双极板的寿命预测模型的建议和验证。首先，基于质子交换膜燃料电池的电化学反应动力学建立了模型。其次，将汽车应用的工况等效为涂层金属双极板的离体加速试验，并建立了基于离体加速试验的模型。最后，通过2500个碳涂层金属双极板组装电堆的现场试验验证了模型的准确性，预测的相对误差为8.68%。该模型的通用性已被评估，通过将其应用到镀金金属双极板，这是测试stedin现场堆栈长达3000小时。该研究有利于涂层金属双极板寿命的快速评估，为涂层的快速发展提供理论指导。
Metallic bipolar plates are considered to be cost-effective and feasible alternative to graphite bipolar plates for high power density of Proton Exchange Membrane Fuel Cells. However, the lifetime of metallic bipolar plates is determined by surface coating and the durability evaluation is extremely costly and time-consuming. It is urgent to establish a method for the lifetime evaluation and quick development of coated metallic bipolar plates. In this study, a lifetime prediction model for coated metallic bipolar plates is proposed and verified. Firstly, the model is established based on the electrochemical reaction kinetics of Proton Exchange Membrane Fuel Cells. Secondly, the operating conditions for automotive application are equivalent to theex-situaccelerated tests for the coated metallic bipolar plates and the model is formulated based on theex-situaccelerated tests. Finally, 2500 hin-situtest of stacks assembled with carbon-coated metallic bipolar plates is carried out to verify the accuracy of the model and the relative prediction error is 8.68%. The universality of the model has been evaluated by applying it to gold-coated metallic bipolar plates, which were testedin-situin stacks up to 3000 h. This study is beneficial to the quick evaluation of lifetime for coated metallic bipolar plates and provides a theoretical guidance for the rapid development of coatings.
