Hydrogen vs. Battery Electric Cars

A FCEV has all the complexities of an BEV least perhaps an on board charger. Add to this the complexities of a problematic fill mechanism, a complex 10,000 PSI tank array. A high tech fuel cell the size of a small engine. It uses 3 times the amount of electricity per mile and you can't just plug it in to get some of the energy straight from your roof top solar.
How, on a level playing field will this compete on price with a BEV?
