Dataset Catalog

This dataset contains standard tests of Nafion 112 membranes and MEA activation tests for PEM fuel cells under various operating conditions. It includes two common electrochemical analysis methods: polarization curves and impedance spectra. Different H₂/O₂ pressures, voltages, and humidity levels are considered. The data enable analysis of PEM fuel‑cell behavior during testing, activation processes, and pre‑/post‑activation phases. Polarization curves show voltage and power density variations as functions of H₂/O₂ flow and relative humidity. Resistance of the equivalent circuit can be derived from impedance data, providing clear cell responses for in‑depth analysis, simulation, and material performance studies in PEM fuel‑cell research.
