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)

Water is the product of using it as fuel. But I don’t know why it’s being touted so much. It’s difficult to store as a gas, much harder as a liquid, and it’s not very energy dense. Longer-term storage is especially difficult because those tiny molecules make their way through almost anything.
Methane is easier to store as gas or liquid, over three times as energy dense as a gas, and it produces CO2 and water. Yeah, yeah, I know, CO2, but if you make it using atmospheric CO2 using clean energy (as you should hydrogen in this same case), it comes out carbon neutral.
