"hydrogen fuel cells ... Not exactly sure why they don't get much more love." Hydrogen is just pretty bad as an energy carrier, since it's so difficult to handle. The main attraction currently is that hydrogen fuel cells are fairly efficient and hydrogen oxidation releases a lot of energy (most of it from the O2 bond, as in most 'combustion') But if fuel cells that can directly handle more complex and more convenient hydrocarbons efficiently can be developed there will be little reason for hydrogen - maybe only cryogenic uses in rockets etc.
