Fuel cell car runs off hydrogen and oxygen.

Fuel Cell car runs off hydrogen and oxygen. The HyRunner car is a reversible PEM (proton exchange membrane) fuel cell car. When the car is filled with distilled water, an external D.C. power supply electrolyzes the water into hydrogen and oxygen (in 2 minutes), stored in separate tanks on the car. After electrolysis is complete, a switch on the car is turned on and the hydrogen and oxygen mix in the fuel cell to supply electrical power to a small electric motor, driving the car. The car moves about 2 inches a second, and will run for 8 minutes. Note: There is a danger of explosion in the presence of sparks or flames. The manual advises using goggles. Operating Instructions: See Fig.1. The car has 2 Plexiglas tanks that are filled with distilled water. On the oxygen tank side of the car, uncap the black rubber Inlet Socket cap, and attach the distilled water bottle. Fill the cylinder up to mark A; then suck back some of the water until it reaches mark B; then put the rubber cap back on. Now, do the same for the hydrogen tank side. When the tanks are filled and the car electrical switch is OFF, plug the D.C. power supply plugs into the Electrolysis Jacks (red into red, black into black). In 2 minutes, the Hydrogen tank will be full, and the Oxygen tank will be half full. Unplug the power supply. The car will run when the switch is moved to ON. See Fig.2. The fuel cell consists of several parts: an anode, a thin sheet of catalyst, a PEM (proton exchange membrane), another sheet of catalyst, and a cathode. The hydrogen anode, or negative terminal, conducts electrons liberated from the hydrogen, and also has channels that disperse the hydrogen over the surface of the catalyst. The catalyst is platinum powder thinly coated onto cloth or carbon paper. The PEM is a thin, semi-porous polymer sheet somewhat like plastic wrap that only allows the transfer of small hydrogen ions, and blocks electrons. The oxygen cathode, or negative terminal, conducts electrons, and has channels that disperse oxygen over the surface of the catalyst. Fig.2 shows both the Electrolyzer Sequence (water is converted into hydrogen and oxygen) and the Fuel Cell Sequence (oxygen and hydrogen combine, liberating electrical power that drives the car).
