The purpose of the presented work is to propose an inventive approach to estimate the aging of a fuel cell submitted to a mission profile. A mission profile can be decomposed in quasi‐static and dynamic sub‐missions. The proposed approach is based on the superposition principle considering that the cell voltage degradation, due to the application of the mission profile, can be determined using the cell voltage degradations experimentally evaluated for all the sub‐missions. In our case, four aging campaigns have been performed: an aging campaign for an aeronautical mission profile and three campaigns for quasi‐static sub‐missions. Each aging campaign consists in around 900 h of profile regularly interrupted to perform characterization phases. The cell voltage degradation attributed to a given solicitation can be estimated using polarization curves carried out during the regular characterization phases, and/or using instantaneous “voltage versus time” curves obtained during the ageing phases. In this paper, results of these campaigns are used to investigate concretely the proposed approach and several examples of application are presented. In all these examples, the results show a good agreement between the experimental cell voltage degradation and the estimated one using superposition principle, attesting of the potential of the proposed approach.

提交任务简报的PEM燃料电池老化估算工具的开发

提出的工作的目的是提出一种创造性的方法来估计提交给任务简档的燃料电池的老化。任务概况可以分解为准静态和动态子任务。所提出的方法基于叠加原理，考虑到由于任务配置文件的应用，可以使用对所有子任务进行实验评估的电池电压降级来确定电池电压降级。在我们的案例中，进行了四个老化运动：针对航空任务概况的老化运动和针对准静态子任务的三个运动。每个老化活动都包含大约900小时的配置文件，这些配置文件定期中断以执行表征阶段。随时间变化的曲线”。在本文中，这些活动的结果用于具体研究所提出的方法，并给出了一些应用示例。在所有这些示例中，结果表明实验电池电压降级和使用叠加原理的估计电压降降之间有很好的一致性，证明了该方法的潜力。
