A "not even wrong" misconception.
At best, a fuel cell MIGHT eventually be SLIGHTLY or SOMEWHAT more
efficient than an ICE.
BUT --
Not one present fuel cell vehicle is remotely as efficient as an ICE.
Fuel cells have an 83 percent maximum theoretical efficiency. This gets
further reduced by inverter (85 percent), motor (90 percent) and wiring
(97 percent) efficiencies, leaving very little possible benefit over the
ICE.
Meanwhile, more people are spending more R&D on the ICE, so its
efficiency is dramatically improving. Perhaps at a one percent per year
rate. Fuel cells are presently falling further and further behind.
They are unlikely to ever catch up.
See http://www.tinaja.com/glib/nrglect2.pdf for more details.
