Zinc or magnesium, how? Magnesium reacts with steam to yield
hydrogen, but now you have to 1) provide water, and 2) heat it to
steam.
Maybe sodium or potassium metal - those react with room-temperature
water to yield hydrogen gas and the metal hydroxide. But still, you
need water: so you have to fill up twice: once with the (hazardous)
metal, and once with water.
Then again there are energy density considerations... compare the
volume and mass of these alternative fuels with those of gasoline.
