RENEWABLE, RECHARGEABLE, INEXPENSIVE ZINC/NATURAL CARBON/GRAPHITE AIR FUEL CELL

摘要

This invention is a metal fuel cell that consumes zinc, oxygen and water. The chemistry of this fuel cell fundamental differs from other previously described metal air fuel cells because water is consumed and zinc and hydroxide anions are adsorbed by the natural carbon compounds of coal, charcoal and biochar. The adsorption of these ions is possible because of the accessible micropore structure of the natural carbon substances. The absorption limits the rate of fuel cell waste thereby decreasing the rate of increase of the cells internal resistance and this chemistry accounts for the fuel cell's longevity. The cell is inexpensive to make and renewable and rechargeable. Development of this cell could have profound effects on environmental, economic and social problems related to global energy.

主权项

1. A metal fuel cell comprising a container, water, air, cathode, anode and a natural carbon substance of coal, charcoal or biochar or any mixtures of these natural carbon substances in which the metal fuel cell consumes a metal, oxygen and water, including fresh water, brackish water, seawater or saline.
