Hydrogen feed gases generated by reformation of fossil fuels contain minute quantities of CO. For use in fuel cells the CO must be removed selectively to prevent fuel‐cell‐catalyst poisoning. T. M. Bernhardt, V. Bonačić‐Koutecký, and co‐workers show in their Communication on page 5467 ff. that sub‐nanometer ruthenium clusters are highly effective at doing so by converting CO into benign CH 4 . Ion‐trap mass spectrometry and DFT calculations identify the properties of these clusters responsible for their selectivity and activity.
