Voltage-Resolved Impedance Data for Polymer Electrolyte Membranes in Fuel Cells

2.3 MB of data from a study proposing a voltage-resolved electrochemical impedance spectroscopy framework for characterizing polymer electrolyte membranes. The dataset, authored by Kirubadurai B and last updated in May 2026, compares the performance of Fumasep FKS-PET-130 and PBI TM2 membranes across a voltage range of 0.3–0.9 V under current-controlled conditions of 5–20 mA.

Use Cases

• Benchmarking proton conductivity based on high-frequency impedance and ohmic resistance values.
• Analyzing voltage-dependent performance based on impedance response across a 0.3–0.9 V range.
• Comparing charge-transfer kinetics between membrane types based on Nyquist semicircle diameters.
• Evaluating polarization and mass-transport losses based on lower-frequency impedance values at 10 Hz.

Strengths

• Includes specific, measured resistance values (e.g., 4–6 kΩ for Fumasep, 20–90 kΩ for PBI TM2).
• Data is collected under defined, controlled operating conditions (voltage and current ranges).
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is DOCX, which may require extraction or conversion for analysis.
