Experimental investigation and comprehensive analysis of performance and membrane electrode assembly parameters for proton exchange membrane fuel cell at high operating temperature

2024-07-30

Abstract:The future trend in proton exchange membrane fuel cells (PEMFCs) is developing towards higher operating temperatures, although the current lack of comprehensive investigation into the PEMFC characteristics at elevated temperatures. This work provides a comprehensive summary of commonly used test methods and data processing methods for PEMFCs, encompassing polarization decomposition, electrochemical impedance spectroscopy (EIS) processing methods, electrochemical surface area (ECSA) and hydrogen crossover current density (iH) calculation methods. Experiments on PEMFC performance and membrane electrode assembly (MEA) parameters at 80 to 95 ℃ under various humidities are conducted. The experimental results indicate that elevated temperatures contribute to increased ohmic loss and reduced mass transfer and activation losses. Increased temperature can substantially accelerate the reaction rate and compensate for the decrease in ECSA. The ECSA decreases at elevated temperatures, and higher temperatures will result in a faster drop. The iH demonstrates an increase with both temperatures and humidities, with higher humidities leading to faster growth. Based on the comprehensive test and analysis methods for PEMFC, this study could enhance understanding and provide valuable guidance for PEMFC performance variation laws at high operating temperatures.
