Chitosan is considered one of the most promising materials for polymer electrolyte membrane fuel cells (PEMFC) due to the high manufacturing cost of the commercial polymer electrolyte membrane (PEM). In this study, chitosan (C-1), chloroacetate chitosan (CCS-21), epoxidized natural rubber (ENR-41), chitosan blended with ENR (CE-6 and CE-7), and chloroacetate chitosan blended with ENR (CCE-26 and CCE-27) based membranes were prepared by solution casting technique and crosslinked with acid and base. The Fourier transform infrared (FTIR) spectroscopy results showed improvements in their peaks, and the atomic force microscopy revealed that the blended membranes had a higher surface roughness than the other membranes. The optical contact angle (OCA) showed that the C-1 had the highest contact angle, while the ENR-41 had the least contact angle. From the electrical measurements, the CCS-21 gave the highest capacitance, conductance, and conductivity. The CE-7 showed the highest resistance and resistivity while ENR-41 showed the highest dissipation factor and dielectric constant. Taken together, CE-7 showed the most suitable characteristics which makes it suitable for use as a PEM.

由于商业聚合物电解质膜（PEM）的制造成本较高，壳聚糖被认为是聚合物电解质膜燃料电池（PEMFC）最有前途的材料之一。在本研究中，壳聚糖（C-1）、氯乙酸壳聚糖（CCS-21）、环氧化天然橡胶（ENR-41）、与ENR共混的壳聚糖（CE-6和CE-7）以及与ENR共混的氯乙酸壳聚糖（CCE） -26和CCE-27)基膜通过溶液流延技术制备并用酸和碱交联。傅里叶变换红外（FTIR）光谱结果显示其峰值有所改善，原子力显微镜显示混合膜比其他膜具有更高的表面粗糙度。光学接触角(OCA)显示C-1具有最高的接触角，而ENR-41具有最小的接触角。根据电气测量结果，CCS-21 具有最高的电容、电导和电导率。CE-7 显示出最高的电阻和电阻率，而 ENR-41 显示出最高的损耗因数和介电常数。总而言之，CE-7 显示出最合适的特性，使其适合用作 PEM。
