Quality control (QC) is an essential part of fuel cell technology industrialization, providing means to reduce cost of components, enhancing the reliability of the final product, and offering specification guidance for new entrants in the supply chain. The membrane electrode assembly (MEA), including membrane, catalyst layer (CL), and gas diffusion layer (GDL), as well as bipolar plate (BP), are key components of a proton exchange membrane (PEM) fuel cell, and the attributes of each component strongly correlate with the cell performance and longevity. To ensure the quality of the fuel cell, it is of great importance to characterize the properties with respect to the standardization of component/sub-component specifications. In collaboration with the fuel cell industry, this work aims at establishing compendiums of attributes, or so-called books of attributes, of key fuel cell components for the QC of PEM fuel cells through reviewing, identifying, categorizing, and prioritizing the main attributes/properties that determine their functionalities. The books of attributes for the major PEM fuel cell components include catalyst coated membrane (CCM) as a sub-assembly, GDL, and BP. To address the full spectrum of fuel cell components, gaskets and sub-gaskets are also included.

质量控制（QC）是燃料电池技术工业化的重要组成部分，它提供了降低组件成本，增强最终产品可靠性的手段，并为供应链中的新进入者提供了规范指导。膜电极组件（MEA），包括膜，催化剂层（CL）和气体扩散层（GDL），以及双极板（BP），是质子交换膜（PEM）燃料电池的关键组件，每个组件的属性与电池性能和寿命密切相关。为了确保燃料电池的质量，就部件/子部件规格的标准化而言，表征特性非常重要。与燃料电池行业合作，这项工作旨在建立属性汇总表，PEM燃料电池QC的关键燃料电池组件的“属性书”（即所谓的属性书），是通过对确定其功能的主要属性/特性进行审查，标识，分类和优先排序来实现的。主要PEM燃料电池组件的属性书包括作为子组件的催化剂涂层膜（CCM），GDL和BP。为了解决燃料电池组件的全部问题，还包括垫片和子垫片。
