Platinum supported on high surface area tungsten trioxide (WO 3 ) has received intensive attention in recent years, mainly because of its improved tolerance towards carbon monoxide (CO) poisoning during methanol oxidation and its enhanced electrocatalytic activity. However, the chemical instability of WO 3 in acid medium is a major issue that hinders its application in fuel cell electrodes...
A series of rare earth cuprates with overall composition Ln 2-x M x Cu 1-y M y 'O 4-δ (where Ln=La and Nd; M=Sr, Ca and Ba; M'=Ru and Sb: 0.0=<x=<0.4 and y=0.1) have been tested as anode electrocatalysts for methanol oxidation. The evaluation of electrode kinetic parameters was made galvanostatically. The catalyst characterization...
