Hydrogen vs. Battery Electric Cars

Going faster with a FCEV? That's not correct. FCEVs have terrible torque and therefore aceleration. The fuel cell is puny, If they are not packing a battery which can dish out the power needed, the car will be slow. At least the the Toyota ones.
Also the more range you need, the more hydrogen you need to pack. Although the mass of hydrogen you carry is not increased too much, the volume is! And to keep the volume low you need to pressurize it, which requires high pressure tanks which in turn are typically heavy! Not to mention the safety hazard to carry a 700 bar tank on your trunk!
