I doubt fuel cells will take off in mass because of many reasons but mostly because H2 is so damn hard to store. Ultimately fuel cells are a tech for electrical storage and at one point they felt logical but as technology improves they begin to have more troubles. Storing hydrogen is just so damn difficult and it needs to be compressed to reach density for mobile applications.
