ABSTRACT:
Renewable fuel cells that produce hydrogen gas, on demand, are used to power a vehicle. When the usable volume of hydrogen gas produced by the fuel cells is depleted, the magnesium anode is converted into magnesium hydroxide precipitate. The magnesium hydroxide precipitate is removed and collected for recycling and the magnesium anode and salt water electrolyte is replaced, thus easily and conveniently re-energizing the fuel cell. The magnesium hydroxide precipitate is recycled to recapture the magnesium which is then formed into new magnesium anodes. The primary power source for the recycling is derived from solar energy. The only waste product produced by the operation of the fuel cell is non-polluting water.
