That's just a minor problem, not a fatal flaw. Obviously you can fix that with a small heater for negligible energy cost.

Commercially available solutions seem to use a flow of nitrogen to purge condensation from the nozzle, which is quite a bit more complicated: https://www.weh.com/en_us/general-news/preventing-the-fuelin...

		Yes, to comply with paranoid hydrogen safety regulations cheaply. Also, note how the nitrogen is also being used to purge the entire line. Not just keep condensation away. With more engineering work an intrinsically safe PTC heater could be certified and used just fine.

Now you have a heater in immediate proximity to hydrogen gas.

It’s not impossible, but I think you’re underestimating the complexity of doing that safely.

Hydrogen ignition temperature is 535°C.

Did you never do the science experiment? One small spark...

		Don’t smoke while fuelling your car. Unless it’s a diesel that is…
