摘要: Abstract It was reported for the first time that electrocatalytic activity of Carbon-supported Pd–Ir (Pd–Ir/C) catalyst with suitable atomic ratio Pd and Ir oxidation formic acid in direct fuel cell (DFAFC) is better than (Pd/C) catalyst, although has no acid. The potential anodic peak at Pd–Ir/C electrode Ir = 5:1 50 mV more negative current density 13% higher Pd/C electrode. This attributed to can promote through pathway because decrease adsorption strength CO on Pd. However, when content too high would be decreased
