This study introduces a novel titanium dioxide carbon nanofiber (TiO-CNF) support for anodic catalyst in direct methanol fuel cell. The catalytic synthesis process involves several methods, namely the sol-gel, electrospinning, and deposition methods. The synthesized electrocatalyst is compared with other three electrocatalysts with different types of support. All of these electrocatalysts differ based on a number of physical and electrochemical characteristics. Experimental results show that the TiO-CNF support gave the highest current density at 345.64 mA mg, which is equivalent to 5.54-fold that of carbon support while the power density is almost double that of the commercial electrocatalyst.
本研究介绍了一种用于直接甲醇燃料电池阳极催化剂的新型二氧化钛碳纳米纤维(TiO-CNF)载体。催化合成过程涉及几种方法,即溶胶-凝胶法、电纺丝法和沉积法。将合成的电催化剂与其他三种具有不同类型载体的电催化剂进行比较。所有这些电催化剂在许多物理和电化学特性方面都有所不同。实验结果表明,TiO-CNF载体在345.64 mA mg时具有最高的电流密度,这相当于碳载体的5.54倍,而功率密度几乎是商业电催化剂的两倍。
