How did the steam get there?

And it's better to use an internal combustion engine than a fuel cell
because?

Because overall (taking everything into acccount) it's VASTLY  more
efficient. Especially with diesels @ 40% thermal efficeincy.

Large bulk carrier ships have diiesel engines that are around or better
50% thermal efficiency.

Uh huh.  Stationary power plants are doing well to hit 50 percent.

And how are either of these better than fuel cells at 80 percent?

You forgot the losses getting the fuel to the cell.

The same losses apply to an internal combustion engine.  Or do you
have some magical new fuel waiting in the wings that can be made more
efficiently than hydrogen?
