Proton conducting materials create prime interest in electro chemical device development. Present work has been carried out to design environment friendly new biopolymer electrolytes (BPEs) using cellulose acetate (CA) complex with different concentrations of ammonium nitrate (NHNO), which have been prepared as film and characterized. The 50mol% CA and 50mol% NHNO complex has highest ionic conductivity (1.02×10Scm). Differential scanning calorimetry shows the changes in glass transition temperature depends on salt concentration. Structural analysis indicates that the highest ionic conductivity complex exhibits more amorphous nature. Vibrational analysis confirms the complex formation, which has been validated theoretically by Gaussian 09 software. Conducting element in the BPEs has been predicted. Primary proton battery and proton exchange membrane fuel cell have been developed for highest ionic conductivity complex. Output voltage and power performance has been compared for single fuel cell application, which manifests the present BPE holds promise application in electrochemical devices.
质子传导材料在电化学器件的开发中引起了极大的关注。本工作旨在设计使用纤维素醋酸酯（CA）与不同浓度的硝酸铵（NHNO）复合的环境友好型新型生物聚合物电解质（BPE），并将其制备成薄膜进行了表征。50mol% CA 和 50mol% NHNO 复合物具有最高的离子电导率（1.02×10Scm）。差示扫描量热法表明，玻璃化转变温度的变化取决于盐浓度。结构分析表明，具有最高离子电导率的复合物表现出更多的无定形性质。振动分析证实了复合物的形成，这已通过 Gaussian 09 软件进行了理论验证。BPE 中的传导元素已被预测。已为具有最高离子电导率的复合物开发了质子电池和质子交换膜燃料电池。已对单个燃料电池应用的输出电压和功率性能进行了比较，这表明目前的 BPE 在电化学器件中有很好的应用前景。
