Overview
IEC TS 62282-7-1:2017 - Fuel cell technologies - Part 7-1: Test methods - Single cell performance tests for polymer electrolyte fuel cells (PEFC) - defines test methods and documentation practices for evaluating polymer electrolyte fuel cell (PEFC) single cells. The Technical Specification covers cell assemblies, test station setup, measuring instruments and methods, performance tests (polarization, steady-state, long‑term, voltammetry, EIS, IR), and required test reporting. It is widely used for MEA testing, single-cell performance characterization, and studying the influence of fuel or air impurities on fuel cell behavior.
Key topics and technical requirements
- Cell components & assembly: guidance on membrane electrode assemblies (MEAs), gaskets, flow plates, current collectors, clamping hardware, temperature control and assembly procedures.
- Test station setup: minimum equipment requirements, schematic arrangements, and inputs/controls for reproducible single-cell testing.
- Measuring instruments & uncertainty: recommended instruments and measurement methods for voltage, current, internal resistance (IR), gas flow, temperature, pressure, and humidity.
- Performance tests:
- Polarization curve tests (constant stoichiometry or constant flow)
- Steady-state and long‑term operation tests
- Voltammetry (including hydrogen crossover and electrochemical surface area/ECA)
- Electrochemical impedance spectroscopy (EIS) and IR measurements
- Applied tests (Annex H - normative): gain tests, stoichiometry tests, temperature/pressure/humidity effects, limiting current, overload, subzero storage/start, membrane swelling (humidity cycling), open circuit voltage (OCV), and ORR activity.
- Test reporting: standardized report items, measurement condition description, and cell parameter documentation to ensure repeatability and traceability.
Applications and who uses this standard
- Fuel cell R&D teams: characterize new MEA formulations, catalyst layers, membranes and gas diffusion materials.
- Test laboratories and certification bodies: establish repeatable single-cell test protocols for comparison, qualification, and performance validation.
- Manufacturers and suppliers: validate materials, detect degradation mechanisms, and assess tolerance to fuel/air impurities.
- OEMs and system integrators: use single-cell data to inform stack design, balance-of-plant requirements, and environmental margins.
- Regulators and standards engineers: reference a harmonized methodology for reporting performance and durability.
Related standards
- Other parts of the IEC 62282 series (fuel cell technologies) and national test-method standards complement single-cell testing with stack- and system-level requirements.
