Hydrogen fuel cells and rechargeable batteries are the two likeliest power sources for tomorrow’s electric vehicles. While economics, convenience, and sustainability will determine which power system dominates, it’s clear that fuel cells have several advantages over batteries. Reviewing these advantages, and some of the drawbacks, may provide insights into where we are headed.
Where Fuel Cells Excel
Fuel cells have a clear advantage when it comes to refueling speed. Although many technologies are being developed for faster battery charging, the physics involved will always be more time-consuming than transferring hydrogen. What’s more, hydrogen refueling is very similar to how gasoline- and diesel-powered vehicles are now refueled: You simply drive up to a pump and fill up your tank. In fact, in its early stages, one or two hydrogen pumps could easily be installed at many…
