Maybe with a supercapacitor in the station and a chrging cable with the diameter of a fuel hose.

I always imagined that portable future wizard (??nuclear??) power would be as simple as unscrewing a 5 gallon cannister from the back of a vehicle and exchanging it at the power/charging station for money. Like the small 20 lb LPG cooking gas tanks. I still think that electric cars are a phase of tech that cannot be sustainable in terms of money and environmental cost and waste for too long and that it is just transitional in our quest. Hydrogen power was always supposed to be the future in my mind.

Hydrogen has extreme structural problems. Hydrogen tanks need constant maintenance, due to how small the molecule is - it's very difficult to contain and prevent corrosion. You then have significant conversion loss between the powerplant-native format of electricity, and the hydrogen. So nothing can be as cheap as pure electricity. Fuelling the car with ammonia that then gets converted to Hydrogen inside the car is the solution to the first problem, but further increases the loss on the second.

What you're describing sounds like a small, high-capacity battery to me! Like a super AA battery. Maybe in 50 years :)
