In this article, we report on the study of the electrochemical characteristics of the electrode material of a proton exchange membrane (PEM) fuel cell containing carbon nanotubes (CNTs) as a functional additive in the oxygen reduction reaction. The data of appraisal by the methods of scanning and transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), differential thermal analysis, cyclic and direct voltammetry on a stationary and rotating disk electrode are given. The results showed that the material has a higher electrode activity in the presence of oxygen-modified carbon nanotubes, a higher half-wave potential of oxygen electroreduction (610 and 500 mV in the presence and absence of CNTs, respectively), showed a threefold higher density of the kinetic current of oxygen reduction, has a 2.5-fold higher density of exchange current in the oxygen reaction. This can be explained by the effect of oxygen-modified CNTs on the content of surface oxide (PtO); in the presence of CNTs, the PtO content is lower.

在本文中，我们报告了质子交换膜（PEM）燃料电池的电极材料的电化学特性的研究，该材料包含碳纳米管（CNT）作为氧还原反应中的功能添加剂。给出了通过扫描和透射电子显微镜（TEM），能量色散X射线光谱法（EDX），差热分析，固定和旋转圆盘电极上的循环伏安法和直接伏安法进行鉴定的数据。结果表明，该材料在存在氧修饰的碳纳米管的情况下具有较高的电极活性，在较高的氧电还原半波电位下（在存在和不存在CNT的情况下分别为610和500 mV）显示出高出三倍的电势。氧气还原动能的密度，具有2。氧反应中交换电流的密度高5倍。可以通过氧改性的CNT对表面氧化物（PtO）含量的影响来解释。在CNT的存在下，PtO含量较低。
