质子交换膜燃料电池（PEMFC）是一种非常有前途的装置。然而，有关系统耐久性和可靠性成本的一些技术限制仍然限制了它们的大规模生产。在此框架下，寿命预测和耐久性增强的研究主要关注。为了解决这个问题，基于预测和健康管理（PHM）的方法被开发出来。值得注意的是，这些方法通常需要建立一个关于系统老化的一致数据库，涉及具体的使命概况。为此，通常进行长期测试。在不同的应用中，本文将集中在两个微型热电联产（μ-CHP）耐久性测试，基于相同的负荷需求。第一个测试在1000小时内完成，而第二个测试减少到500小时，得到压缩曲线。我们观察到，各自的全局电压退化率是相似的。因此，提出了一个反射，以支持加速测试协议的发展。(C)2016年氢能出版有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
Proton exchange membrane fuel cells (PEMFC) are extremely promising devices. Nevertheless some technological constraints concerning system durability and reliability costs, still limit their large-scale production. In this framework, lifetime prediction and durability enhancement studies are mainly concerned. To solve this issue, methods based on Prognostic and Health Management (PHM) are developed. It is worth noting that these methods usually require to establish a consistent database concerning the system ageing referring to specific mission profiles. To this purpose, long-term tests are commonly performed. Among different applications, this paper will focus on two micro-cogeneration (mu-CHP) durability tests, based on the same load demand. The first test is realized in 1000 h while the second one is reduced to 500 h resulting in a compressed profile. We observed that the respective global voltage degradation rates are similar. Consequently a reflection is proposed to support accelerated tests protocol development. (C) 2016 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
