Stack-Test – Development of EU-wide uniform performance test schemes for PEM fuel cell stacks Test Module 2.18 – Electrochemical Methods

Kurzfassung

Objective of the Test Module: To provide a standardized description of a common set of electrochemical methods that find good use for in-depth characterization of the operation of PEM fuel cell stacks. Document Contents: In-stack electrode voltammetry (including CO and methanol stripping) H2-PEMFC and DMFC stack electrochemical impedance spectroscopy (EIS) H2 crossover in H2-PEMFC stack Methanol crossover in DMFC stack Anodes’ steady-state polarization curves in DMFC stack Test equipment and setups Test inputs and outputs Test procedures descriptions Data post processing Recommended ranges for test parameters References
