Hydrogen Fuel Cells???

Question

If someone works out how to use Hydrogen Fuel Cells for energy, will that cause problems with the seas???

And how will that affect the global stability???

Answer 1

I can't think of any problems with the seas that would be caused by widespread use of hydrogen fuel cells.

Answer 2

if some one does works out how to make hydrogen fuel cells (which i think they already have) they would surely make sure that it causes minimum damage.

     it might be true that seas(water from it) will be used as a fuel(since water is more abundant than hydrogen) which would be broken down to get hydrogen.

   there could be problems like lowering of water level in the sea but i thing in cars and bus (where this technology is used) the are giving out water  vapor from their exhaust. so surely it is like water goes in and water comes out, so the problem is solved.
