I have basic idea of working of hydrogen fuel cell but why just hydrogen? Isn’t there any better or maybe cheaper alternative?
(I know it’s bit complex for but I would appreciate your answers)

Hydrogen is an element; it contains no carbon. Therefore, it has zero carbon emission. Every other common fuel is some kind of carbon compound and has non-zero carbon emission. Also, hydrogen can be made from water using any zero-emission energy source (nuclear, hydro, solar, wind, you name it). Well, it can also be made from water using a coal burning power plant, but it kinda defeats hydrogen’s purpose.
