It actually isn't. Hydrogen filling stations can only fill a couple of cars in a row before they need time to pump hydrogen from the storage tank to the buffer tank and compress and cool it to -40 degrees. So the number of cars they can handle in a day is not massively higher than a DC fast charger.
If it doesn't have time to prepare between vehicles, it starts taking 20 minutes to fill each vehicle.
