Many obstacles stand in the way of ditching the internal combustion engine in favor of electric motors feeding off hydrogen fuel cells. Such a change would require new infrastructure for the delivery, storage, and distribution of hydrogen, either in a low-temperature, liquid state, or at high pressure, as a room-temperature gas. And standard hydrogen fuel cells are expensive, requiring as much as 100 grams of platinum at a cost of thousands of dollars.
