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
