Definitions

  • the invention relates to fuel cells, and more specifically to the production of hydrogen and oxygen to feed fuel cells.
  • Prior Art As the number of cars, trucks and buses on the road increases, the need for alternatives to the internal combustion engine burning hydro-carbon fuels becomes ever more apparent. The largest of the world's oil reserves are in the politically unstable Middle East and in any event cannot last indefinitely. The health hazards posed by nitrogen oxides and other compounds in vehicle exhausts produced by the somewhat inefficient combustion of hydrocarbon fuels are well known, and concern about emissions of the greenhouse gas carbon dioxide are also growing.
  • Fuel cells and fuel cell technology have been known to be a clean, non-polluting means of producing electricity from hydrogen and oxygen for many years. In 1839 a British physicist demonstrated that the electro-chemical union of hydrogen and oxygen generates electricity, electrochemical engines, or fuel cells, based on this concept remained little more than laboratory curiosities for more than a century.
  • Fuel cells comprise a pair of electrodes contained within a non-conductive container sandwiching an electrolyte therebetween which allows ions to flow but not electrons therethrough, which electrically connects the respective electrodes inside the container of the fuel cell.
  • Hydrogen in the form of a fuel is supplied to the anode, or negative electrode, which reacts there by liberating electrons and forming positively charged hydrogen ions.
  • the electrons flow as a current through an external circuit and load, such as an electrical motor, to the cathode, or positive electrode.
  • the hydrogen ions flow through the electrolyte also to the cathode, where the electrons and hydrogen ions combine with the hydrogen ions and with oxygen supplied in the form of an oxidizer, producing water as the only waste product.
  • the efficiency of the direct chemical-to-electrical energy conversion in a fuel cell is theoretically very high, but in practice is much lower. This is because of the slow reaction rate of the oxygen atoms with the hydrogen ions and the electrons at the cathode. Catalysts such as platinum speed the reaction rate of the oxygen atoms, but achievable efficiencies are still only between about forty-five and sixty percent, even using the best platinum or platinum-alloy catalysts. This is still better than internal combustion engines , which might reach thirty-five percent efficiency under ideal conditions, but in actual operation average only about fifteen percent efficiency.
  • Alkaline fuel cells can function with much less platinum than acid-based fuel cells can.
  • Alkaline fuel cells wherein the fuel used was compressed hydrogen gas and the oxidizer used was compressed oxygen, were the first type of fuel cell to be used to produce electricity to power a motor vehicle, an Allis-Chalmers farm tractor back in 1959.
  • Alkaline fuel cells can be made from inexpensive material with the whole case thereof being injection molded plastic.
  • the hydrogen which is produced is up to 99.99 percent pure, being essentially free of carbon dioxide and other contaminates.

  • the electrical output of the fuel cell be greater than when using prior art hydrogen and ambient air delivery devices due to a greater reduction in carbon dioxide entering the fuel cell, oxygen by volume thus being present in a greater percentage in the ambient air supplied to the fuel cell, thus allowing more transference of electrical potential and greater electrical power output.
  • the alkaline metal utilized is sodium or sodium hydrates, that the sodium hydroxide by-product produced during the production of hydrogen be utilized for removing the carbon dioxide from the ambient air supplied to the fuel cell.
  • a hydrogen delivery device of the invention for generating and supplying hydrogen gas on demand and for removing carbon dioxide from the air supplying oxygen to a fuel cell.
