Solar Hydrogen kit allows you to create clean energy using fuel-cell and renewable hydrogen created using sun and water.

An educational device ideal for schools, it could be used in science labs or directly in class.

The kit contains a solar cell kit, a reversible PEM fuel-cell and hydrogen and oxygen tanks: you need just distilled water to start your kit and to produce hydrogen and electrical energy.

Solar Hydrogen Kit�s use is very easy. Linking the solar panel to the fuel-cell, the fuel-cell can work as an electrolyzer separating water molecule in hydrogen through the electrolysis. Hydrogen and oxygen are stored in 2 transparent tanks. Then the fuel-cell can transform hydrogen chemical energy in electrical energy thanks to a very easy and reliable chemical process, reverse electrolysis in which hydrogen bind oneself with oxygen.

The reactions which happen inside of the fuel-cell are redoxes:

  electrolysis mode (electrolyzer):  

 -  anodic reaction (oxidation): H2O > � O2 + 2 H+ + 2 e-
 - catodic reaction (reduction): 2 H+ + 2 e- > H2

 Reverse electrolysis mode (fuel-cell):

- anodic reaction: H2 > 2 H+ +e-

- catodic reaction: � O2 + 2 H+ + 2 e- > H2O

Electrical Energy produced by the fuel-cell moves a little blade when the cables of the motor are linked to the fuel-cell. Hydrogen and oxygen stored are so used.

Solar Hydrogen Kit should only be used by persons 12 years old and up and only under the supervision of an adult.
