碱性聚合物电解质燃料电池电极疏水性对性能的影响
Influence of Electrode Hydrophobicity on Performance of Alkaline Polymer Electrolyte Fuel Cells
摘要
Abstract
In the present work,we study the influence of the electrode hydrophobicity on the performance of alkaline polymer electrolyte fuel cells(APEFCs).QAPS or xQAPS is employed as the membrane and the ionomer,while PTFE is used as a hydrophobic additive in order to adjust the electrode hydrophobicity.We find that enhancing the hydrophobicity of anode can promote the performance of APEFCs,while a moderate hydrophobicity of cathode is required to achieve optimal performance.By using xQAPS as the electrolyte and adding some PTFE in the anode,a peak power density of 132 mW ·cm-2 can be obtained at a current density of 280 mA·cm-2 when the APEFC single cell is operated under 100％ RH at 60 ℃.关键词
