* Hydrogen fuel-cell vehicles would be unsustainable to scale up, because of the [[?|amount of platinum & palladium in the fuel cells]]. {{talk|This page needs to mention: Hydrogen ''production'' also requires these same metals but it [[?|can be done with much less of them]] and thus could probably be done sustainably.}} | * Hydrogen fuel-cell vehicles would be unsustainable to scale up, because of the [[?|amount of platinum & palladium in the fuel cells]]. {{talk|This page needs to mention: Hydrogen ''production'' also requires these same metals but it [[?|can be done with much less of them]] and thus could probably be done sustainably.}} | ||
