Pros and Cons of Hydrogen Fuel Cell Vehicles

One big “con” — is this the price of convenience? Even the least efficient BEVs get in the upper 80 MPGe range, and more efficient ones are rated 100-120 MPGe.
“The energy efficiency of a fuel cell is generally between 40–60 percent, or up to 85-percent efficient in cogeneration if waste heat is captured for use, said Plug-in America’s Chief Science Officer Tom Saxton. “FCVs do not do cogeneration. So, automatically, they throw away half of the energy in the hydrogen. EV’s are 90 percent or more efficient from battery to wheel. Add to that the energy loss using electricity to convert water to hydrogen.”
