Ah, the magical technological advancement that is only possible with hydrogen. While ignoring the advancements with EVs.

At the moment, hydrogen production is too costly, energy wise.

EVs are already way more efficient. You're repeating things that have been discussed ages ago as something new.

A fuel cell car is an EV.

But it's an electric car with a much lower efficiency than one that uses batteries

A highly exaggerated claim. Once you factor in all of the challenges of grid energy storage and battery manufacturing, there's likely to be little to no difference.

Ok calm down, you don't need to be condescending.

I know that right now hydrogen production is really not efficient compared to simply recharging a battery. Producing hydrogen takes more electricity to produce from water electrolysis to fuel a car for the same range as it would take to simply charge a battery. This I am aware of. And that's what I was implying in my previous comment.

However, a small hydrogen cell powered car has at least twice the range of a similar sized EV. And also, it doesn't take hours to recharge. Only a few minutes to refill the hydrogen tank.

What I hope it that we one day find a way to efficiently produce hydrogen. Because I'd rather have to wait a couple of minutes to refuel on a long trip than having to stop for an hour every time I need to recharge.

We have a more efficient way to produce hydrogen, which is using nagural gas. That's obviously a bad idea. You can't change the laws of physics, producing hydrogen from water and electricity just takes that much energy.

Yeah I know that. That's why initially I was saying it would be great if we found a better more efficient way to produce it. Obviously hinting at the fact that it wasn't the case right now.
