我们使用磁共振成像（MRI）来检查运行中的燃料电池内聚合物电解质膜中的水含量分布。在研究的三种厚度中，较薄的膜比最厚的膜水合较少。此外，膜中的总水含量随着电池电流的增加而降低。我们还使用电化学阻抗谱检查了MRI结果，发现光谱结果与成像结果一致。
We used magnetic resonance imaging (MRI) to examine the distribution of the water content in a polymer electrolyte membrane within an operating fuel cell. Of the three thicknesses studied, the thinner membranes were less hydrated than the thickest membrane. In addition, the total water content in the membranes decreased with an increase in the cell current. We also used electrochemical impedance spectroscopy to check the MRI results and found that the spectroscopy results agreed with the imaging results.
