Deep‐cleaned hydrogen can be made available for fuel cells in one step. 1 vol % CO contained in hydrogen was removed to levels of less than 10 ppm over ruthenium‐doped mesoporous Ni‐Al oxides (see picture) by selective CO methanation, with a working temperature window greater than 50 °C that included the 200–250 °C range. The catalysts exhibited excellent long‐term stability.
