The effect of precipitants on Ni-Al2O3 catalysts prepared by a co-precipitation method for internal reforming in molten carbonate fuel cells

► The effects according to kinds of precipitants in the Ni-Al2O3 catalysts were observed. ► The precipitant effects via physicochemical properties, XRD, H2-TPR and SEM were realized. ► The catalysts were compared with respect to their performances for methane steam reforming.
