Scope

GB/T 28817-2022 is the English-translated version of 聚合物电解质燃料电池单电池测试方法.

GB/T 28817-2022 is the Chinese standard "Single cell test methods for polymer electrolyte fuel cell (PEFC)". Its scope clause reads: This document covers assemblies, test station setup, measuring instruments and measuring methods, performance test methods, and test reports for PEFC single cells.

Note: The polymer electrolyte fuel cell single cell fuel specified in this document is gaseous hydrogen.

This document is used for evaluating the following three items: a) the performance of membrane electrode assemblies (MEAs) for PEFCs; b) materials or structures of other components of PEFCs; c) the influence of impurities in fuel and in air on the cell performance.

Note: This document is only applicable to proton exchange membrane fuel cells. Other polymer electrolyte fuel cells can refer to the test content of this document. Its clauses include terms and definitions.
