The Mirai still has a small lithium battery like a hybrid since fuel cells cannot put enough instantaneous power (only 128kw and has start up time) for normal driving they need a buffer battery that is recharged by the fuel cell. Since this battery is so small it can't benefit as much from regen like a normal BEV and has pretty poor performance as well (182hp). All this in a car that weighs more than an equivalent BEV due to heavy 10,000 psi hydrogen tanks and complexity with the fuel cell and buffer battery.
I personally believe hydrogen is a dead end for automobiles, the end to end efficiency is much worse (creating and compressing hydrogen) vs just charging a battery not to mention the issues of storing a transporting hydrogen safely [2].
