CuMnOx catalysts for internal reforming methanol fuel cells: Application aspects

► CuMnOx catalysts for Internal Reforming Methanol Fuel Cell. ► Incorporation of reformer into the anodic compartment of high temperature PEMFC. ► Phosphoric acid leaching affects the performance of the internal reforming catalyst. ► Prereduced catalysts more active but more sensitive to phosphoric acid attack. ► Satisfactory operation at 200 °C for 350 h in the presence of MEA.
