Abstract: A method for the treatment of a methanol reforming catalyst includes pre-aging the catalyst by baking it out in a dry atmosphere in order thereby to complete its inherent initial loss of volume before the start of the methanol reforming reaction. The method may be used for methanol reforming reactors in fuel-cell-operated motor vehicles.
