Degradation behaviors of polymer electrolyte membrane fuel cell under freeze/thaw cycles

【摘要】:正Degradation behaviors of polymer electrolyte membrane fuel cell(PEMFC) in high current density region were investigated under Freeze/Thaw cycles in this study.Different dehumidification scenarios namely hot purge,cold purge and no purge were adopted for comparison.Polarization curves and power density curves were utilized to compare the cell
