The kit consists of a Fuel Cell Car Kit and a Solar Hydrogen Energy Education Set both by Horizon Educational.Horizon's Fuel Cell Car Science Kit enables students to discover the principles behind the real-scale fuel cell vehicles currently being rolled out across the world. Generate hydrogen through water electrolysis and convert it into electricity using a PEM fuel cell which then powers the car. The Fuel Cell Car is capable of driving itself - capable of negotiating obstacles independent of the user.The Solar Hydrogen Energy Science Kit demonstrates the workings of a clean energy technology system on a miniature scale. Power an electrical circuit by solar panel or a wind turbine with profiled blades based on NASA aeronautics.Whichever combination of technologies you want to explore this science kit is a comprehensive introduction to the principles behind renewable micro-grids.Includes Full STEM Activity Materials for:Reversible electrolysis reactionsReaction ratesConservation of energy and energy transferRenewable energy
