Chemistry being sloppy, fuel cells are unlikely to have zero emissions.

The question is which will have higher emission per unit of power. I’m betting fuel cells will be better given the are likely to have better fuel efficiency and probably have fewer emissions.

Here's an excellent article that addresses the questions about ammonia ICE engines:

It includes a table comparing various fuels, showing the energy density / storage space required for each, and their emissions, compared to HFO (heavy fuel oil).
