An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

A fuel cell generates power through an electrochemical reaction, not combustion. So no, even if we went to hydrogen fuel cells, the ICE engine is done.

But you will burn the hydrogen to release the energy in some form. That would seem to indicate some form of combustion would it not?

Fuel cells don't burn the hydrogen. There is no combustion.
