聚合物电解质燃料电池作为清洁、高效的发电装置，可以解决能源枯竭、全球变暖和环境污染等问题而备受关注。在这项研究中，我们采用聚合物涂覆的纤维素纳米晶体和不同的粘合剂树脂制造了质子传导填料填充的膜。此外，我们还证明了质子传导率与粘合剂树脂吸水率之间的关系。结果表明，所制备的具有高吸水率的膜在高湿度和低温下表现出优异的质子传导性能，并且质子传导的活化能较低。吸水率与质子传导功效之间相容关系的证实有助于设计和制造新的粘合剂树脂合成模型，并有助于了解聚合物骨架结构以提高聚合物电解质膜的质子传导性能。
Polymer electrolyte fuel cells are attracting attention as clean, highly efficient power generation devices that can solve problems such as energy resource depletion, global warming, and environmental pollution. In this research, we have fabricated proton conductive filler-filled membranes, employing polymer-coated cellulose nanocrystals and different binder resins. Moreover, we have demonstrated the relationship between proton conductivity and water uptake of binder resins. It was clarified that the fabricated membrane with a high water uptake ratio showed excellent proton conduction performance under high humidity at low temperatures with a low activation energy for proton conduction. The substantiation of the compatibility relationship between water absorption and efficacy of proton conduction can contribute to the design and fabrication of a new binder resin synthesis model and contributes to the knowledge of the polymer skeleton structure for the improvement of the proton conductive performance of polymer electrolyte membranes.
