This document 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:

  1. the performance of membrane electrode assemblies (MEAs) for PEFCs in a single cell configuration;

  2. materials or structures of PEFCs in a single cell configuration; or,

  3. the influence of impurities in fuel and/or in air on the fuel cell performance.
