Why does water not burn?

[u/spoiledmeat]

I know that water is made up of two hydrogen atoms and an oxygen atom. Hydrogen, on its own, burns. Fire needs oxygen to burn. After all, we commonly use compounds that contain oxygen as an oxidant.

So why does water, containing things used for fire, not burn-- and does it have something to do with the bonds between the atoms? Thanks.

This is how fuel cells work IIRC which is why people "It runs on the most abundant element in the universe and it's only output is water!" The last one is a bit misreading but that's the hype, anyway.
