I think the two biggest sellers of Hydrogen electric over battery electric, are the fact that batteries have a useful life. That life degrades over time. Hydrogen doesn't have this characteristic. Secondly, cold weather doesn't affect Hydrogen electric vehicles the way that it does with battery electric. If one lives in a cold weather climate, owning a Tesla isn't as advantageous.

Both the pressure tanks as well as the fuel cells themselves degrade over time and need to be maintained and replaced.

absolutely wrong. Hydrogen fuel cells absolutely degrade over time (they are batteries! Just with more maintenance required due to needing fluids pumped through them). Their lifetime for automotive applications is about 5000 hours, or 150,000-200,000 miles, which is less than what a Model 3’s battery will last. https://www.hydrogen.energy.gov/pdfs/progress18/tahi_lohse-busch_2018.pdf https://www.hydrogen.energy.gov/pdfs/progress18/tahi_lohse-b... Cold weather isn’t a major problem, either, you just will want to get a heat pump option. Electric cars are insanely popular in Norway, and it doesn’t seem to be a significant problem.

  they even need a battery aswell which will wear. since the cell is too sluggish to be fed directly to the electric motor.

Eh, it's fine. Norway is the EV capital of the world. Range is decreased, but it's not really a problem in day-to-day driving. We have an older 30kWh EV, with less than 100km range in winter. It's almost never an issue. Even driving 2 hours to a cabin is fine with a fast-charge that takes less time than buying groceries next to the fast charge station. In colder climates, it's more common for people to have garages where they can charge at home. There are even colder areas, and remote areas where the range really is a big issue, but then we're talking about areas with very small populations. If all of them continue to drive diesel cars, it'll be a microscopic blip in terms of global CO2 emissions.
