Effect of synthetic modifier on the performance of DMFC anode electrode

In this study, in order to reach a new suitable electrolyte for better methanol electro-oxidation in acidic media, solution containing synthetic modifier (SM) was used.These SMs have high thermal stability and excellent ionic conductivity which has conductivity about 0.1 S/cm. The methanol oxidation was monitored on modified GC electrode with 10-20 %wt Pt-Ru/C which has Pt and Ru loading of 0.051 mg/cm2 and 0.102 mg/cm2, respectively. SMs improve the methanol oxidation reaction kinetic by increasing the solution ionic conductivity and also decrease the RCT of reaction. Therefore, SM added electrolyte can be the new promising electrolyte for DMFCs application.
