Seriously, if a chemical has to be carried onboard and is transformed thru
some process (perhaps even using seawater) to produce the hydrogen to be
consumed in the fuel cell, then what is that chemical, other than a fuel?

A catalyst.

As with anything associated with the "hydrogen economy", spend some time
researching how these substances are produced.

Never said I thought it was a magical miracle cure. Just asked whatever
became of it.
