Highly active catalysts for the methanol steam reforming (MSR) capable of operating efficiently at the same temperature of high temperature polymer electrolyte membrane fuel cells (HTPMFCs) devices are strongly desired. A novel CuO/ZnO/Ga2O3 catalyst was synthesized by co-precipitation method and characterized by ICP-AES, N-2-physisorption, SEM-EDX and XRD. This catalyst showed a catalytic activity 2.2 times higher than commercial CuO/ZnO/Al2O3 catalysts at 453 K Two kinetic models one empirical and one mechanistic were applied to describe the methanol steam reforming reaction over one of the most promising catalyst family.
