壳聚糖修饰甲醇燃料电池PtRu催化剂

Chitosan modified PtRu catalysts in methanol fuel cells

利用化学沉积法将壳聚糖(Chitosan)修饰于直接甲醇燃料电池(DMFC)阳极催化剂中,制得PtRu/CNT-CS催化剂,并考察了其对甲醇的电催化氧化性能。壳聚糖的修饰使甲醇氧化的电流密度由29.3 m A/cm^2增加到44.8 m A/cm^2,电荷转移电阻明显减小。

Chitosan was introduced into the electro-catalyst of direct methanol fuel cell （DMFC） as an additive, and they were applied to investigate the electrocatalytic activity of the electrode for methanol oxidation. The current density of the methanol oxidation reaction increased from 29.3 mA/cm2 to 44.8 mA/cm2. The charge transfer resistances decreased obviously.
