Are Hydrogen Fuel Cells Better Than Lithium-Ion Batteries?

First, hydrogen is clean energy that doesn''t put out any emissions. Second, hydrogen has more "energy density" than a typical lithium-ion battery in an electric vehicle. That means we can get more energy per unit of hydrogen than we can from an equivalent unit of energy from lithium-ion batteries. But there''s just one problem.
