   I don’t think ammonium hydroxyfluoride exists in the first place :). Do   
   you mean hydrofluoride – NH4HF2? I doubt it can work as fuel. It’s   
   non-flammable, and although it can decompose to gases at high   
   temperature (expanding gas can power something), the costs would   
   probably be enormous and the products are extremely corrosive and toxic.
