Science Mag: Battery-powered cars may be on the cusp of the mainstream auto market, but scientists and car makers still have high hopes for hydrogen fuel cell vehicles, which should refuel faster and travel longer distances between fill-ups. Hydrogen fuel cells have their own Achilles’ heel, however: They are easily poisoned by carbon monoxide (CO). Now, researchers report that they’ve created novel catalysts for fuel cell cars that strongly resist carbon monoxide contamination, potentially solving a …
