hydro-Genius Fuel Cell Car
Atoms and Subatomic Particles Atoms are composed of Protons, Neutrons, and Electrons Protons are positive, neutrons are neutral, and electrons are negatively charged Everything is made of atoms + ++ + -- - -
+ Electrons that create the current split the water molecules Resulting gases are pulled to separate tubes Electrolysis H Energy O O H H H - Opposites Attract O H H O H H
Chemical Equation for Electrolysis (Hydrolysis) 2H 2 O 4e - + O 2 (g) + 4H + Net: 2H 2 O (l) 2H 2 (g) + O 2 (g) 4e - + 4H 2 O 4OH - + 2H 2 (g)
Chemical Equation for Fuel Cell 2H 2 (g) 4e - + 4H + Net: 2H 2 (g) + O 2 (g) 2H 2 O (l) O 2 (g) + 4e - + 2H + 2OH -
