Ni-Pt sinter as a promising electrode for methanol electrocatalytic oxidation

摘要

Methanol is one of the chemical compounds utilized in fuel cells. The direct methanol fuel cell (DMFC) can be applied in many devices such as light electric vehicles and field equipment. Such a fuel cell is characterized by its high fuel energy density and low pollution. Despite many advantages of DMFCs, they are not commercially available, as the most efficient catalyst, which can be used in this process, has not been developed yet. Traditionally, it was platinum that was used in these fuel cells which is expensive and susceptible to CO poisoning. The solution to this is the use of bimetallic catalysts such as a Ni-Pt system. In this study, we used a sintered Ni-Pt electrode as the anode for the electrocatalytic oxidation of methanol. Based on our results, the sintered Ni-Pt electrodes exhibited much higher activity in the oxidation of methanol, when compared with some conventional anodes.
