质子交换膜燃料电池关键材料理化参数测试数据集

燃料电池的使用期间变化的操作条件带来电池内部电极电位、反应气量、水、热状态的改变，会导致电堆关键材料如质子交换膜、催化剂、炭纸、极板基材及涂层等发生化学或机械衰减，造成性能损失并最终降低耐久性，缩短使用寿命。为了延长电池的使用寿命，研究了关键材料特征理化参数的衰减行为，并分析了相应衰减机理。本研究有助于提高燃料电池耐久性，进而降低使用成本，对燃料电池商业化应用具有重要的意义。Fluctuating operating conditions during fuel cell operation alter the internal electrode potentials, reactant gas fluxes, water and thermal states of the stack. Such changes will induce chemical or mechanical degradation of critical stack materials, including proton exchange membranes (PEMs), catalysts, carbon papers, bipolar plate substrates and coatings, leading to performance loss, reduced durability and ultimately shortened service life. To extend the service life of fuel cells, this study investigated the degradation behavior of the characteristic physicochemical parameters of these critical materials and analyzed the corresponding degradation mechanisms. This research contributes to enhancing fuel cell durability, thereby lowering operating costs, and is of great significance for the commercialization of fuel cell technology.
