IEC TS 62282-7-1:2017

Fuel cell technologies - Part 7-1: Test methods - Single cell performance tests for polymer electrolyte fuel cells (PEFC)

IEC TS 62282-7-1:2017(E) covers cell assemblies, test station setup, measuring instruments and measuring methods, performance test methods, and test reports for PEFC single cells. This document is used for evaluating:
- the performance of membrane electrode assemblies (MEAs) for PEFCs in a single cell configuration;
- materials or structures of PEFCs in a single cell configuration;or
- the influence of impurities in fuel and/or in air on the fuel cell performance.
