聚电解质膜是质子交换膜燃料电池的重要组成部分。Nafion是一种商业上已知的膜，其在低温下操作的PEM燃料电池中给出令人满意的结果。本论文主要研究聚醚醚酮（PEEK）聚合物的膦酸功能化。在镍基催化剂的帮助下进行官能化。此外，通过FTIR、EDAX、DSC、TGA和1H NMR对聚合物进行了表征，并且发现PEEK聚合物被膦酸基团官能化，与原始PEEK相比具有良好的热稳定性。最后，功能化聚合物的薄膜制备的溶液浇铸法，和膜样品的质子电导率的阻抗谱测量其值被发现是令人满意的具有良好的热稳定性相比，市售的Nafion膜。
Polyelectrolyte membrane (PEM) is an important part of PEM fuel cell. Nafion is a commercially known membrane which gives the satisfactory result in PEM fuel cell operating at low temperature. Present research paper includes functionalization of Poly(ether ether ketone) (PEEK) polymer with phosphonic acid group. The functionalization was done with the help of nickel-based catalyst. Further, the polymer was characterized by the FTIR, EDAX, DSC, TGA, and 1H NMR, and it was found that PEEK polymer was functionalized with phosphonic acid group with good thermal stability in comparison to virgin PEEK. Finally, the thin films of functionalized polymer were prepared by solution casting method, and proton conductivity of film samples was measured by impedance spectra whose value was found satisfactory with good thermal stability in comparison to commercially available Nafion membrane.
