Abstract This research reports fabrication of three Polymer Electrolyte Membrane fuel cells (PEMFC) using composite of gold nanoparticles and nanotube graphene by varying concentration of Gold nanoparticles. The outer most layer of multiwall carbon nanotubes is un-zipped and nano ribbons of graphene are developed to attain a durable electrode. Moreover, the addition of gold nanoparticles adds benefit of better conductance over usual platinum electrodes. The effect of changing gold concentration on properties of composite material as well as fuel cell performance is investigated. The presence of gold nanoparticles and graphene nano-ribbons attached to carbon nanotubes are identified using SEM, TEM, and Raman analysis. Cyclic voltammetry analysis has showed that increase in concentration of gold nano particles improves the performance of fuel cell. EIS analysis reveled that the polarization resistance decreased by increasing the Au concentration. Thermal Gravimetric Analysis proved the thermal stability of composite material. Maximum power density of 242.29 mWcm−2 is achieved for the highest concentration of Gold nanoparticles.

摘要 本研究报告了通过不同浓度的金纳米粒子使用金纳米粒子和纳米管石墨烯的复合材料制造三种聚合物电解质膜燃料电池 (PEMFC)。多壁碳纳米管的最外层被解开，石墨烯纳米带被开发出来以获得耐用的电极。此外，金纳米粒子的添加增加了比普通铂电极具有更好电导率的好处。研究了改变金浓度对复合材料性能和燃料电池性能的影响。使用 SEM、TEM 和拉曼分析确定金纳米粒子和附着在碳纳米管上的石墨烯纳米带的存在。循环伏安分析表明，金纳米颗粒浓度的增加可提高燃料电池的性能。EIS 分析表明，随着 Au 浓度的增加，极化电阻降低。热重分析证明了复合材料的热稳定性。最高浓度的金纳米粒子可实现 242.29 mWcm-2 的最大功率密度。
