| Splitting Water |
| Hydrogen From Electrolysis |
| Easy Lab |
| Remove erasers and metal | |
| Sharpen both ends of the pencils | |
| Set pencils into glass of water | |
| Attach battery to pencils | |
| Hydrogen bubbles collect on negative lead, oxygen on the positive lead | |
| Does not create enough hydrogen to be dangerous |
| Fuel Cell |
| Hydrogen fuel is fed into the "anode" of the fuel cell. Oxygen (or air) enters the fuel cell through the cathode. Encouraged by a catalyst, the hydrogen atom splits into a proton and an electron, which take different paths to the cathode. The proton passes through the electrolyte. The electrons create a separate current that can be utilized before they return to the cathode, to be reunited with the hydrogen and oxygen in a molecule of water. | |

| FUEL CELL |
| First Fuel Cell Home In 1998 | |
| Natural Gas | |
| 7 kW output | |
| Expected market price $3,000-$5,000 |
| 7 kW Residential power |
| PEM (proton exchange membrane) | |
| Platinum cost was $9,000, now $50 | |
| 40% efficiency up to 70-85% when heat is used | |
| $.07-$.10 per kW |
