To be fair, there is likely some fire to go with the smoke. Regular vehicles which are only driven short distances can collect water in the exhaust which can lead to corrosion. Hydrogen vehicles might experience something similar. And I guess fuel cell exhaust would not reach similar temperatures to an ICE exhaust. But I'm sure the system could easily be designed to ensure icing up would not be a problem.
