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 seen as the closest to an ideal fuel because both production and consumption of it can be (almost) 100% green and renewable.
Some have mentioned that you get mostly water when you consume hydrogen.
On the production side, the ideal pathway is to use electricity from solar energy (hence no emission) to break down water into hydrogen and oxygen (no unwanted emission too!)
There are also other similarly green fuel, known as e-fuel, but they are a long way away from being widely commercially available.
