Actually, the theory says that during the inflationary period, the Universe was *driven* to be flat, as opposed to open or closed, because of the nature of inflation and vacuums. Once we understood that the Universe could be open, closed, or flat (1930s?), we were shocked to find that it had won the lottery -- it's flat (probably).
Fuel cells *do* work by recombining hydrogen with oxygen to create water and electricity. Laptops eat electricity; the (ultrapure) water would be 'waste'. So to run water into the laptop, break it apart, and then recombine it would ultimately be a futile exercise, thanks to thermodynamics (throw heat in there and you've got an inefficient system). Ethanol or other fuels would be the carrier of the needed H.
