Part 4. About the solar hydrogen education kit

The kit demonstrates chemistry and physics principles by experimenting with the splitting of water into

its basic elements using direct renewable power generation from solar photovoltaic technology. Watch

the initial process of electrolysis (See page 6 for more information on electrolysis) using the reversible

fuel cell enabling hydrogen and oxygen to be produced and stored. Learn how hydrogen can be used

as a renewable “energy carrier” that can power many applications via fuel cell technology.

This kit provides an excellent opportunity to learn about the exciting prospects of renewable energy.

See how renewable energy can be harnessed, stored, and re-used in all kinds of applications and how

hydrogen can be the unique link between natural sources of power and power consuming devices -

using fuel cell technology.

Enjoy this exciting science education kit, and start building your own hydrogen powered world!
