Winner of a Parent's Choice Gold Award, this is the experiment kit that provides children with a fun, hands-on way to discover fuel cells by building their own hydrogen-powered zero-emission vehicle. The kit uses solar panels and a proton exchange membrane fuel cell to separate water into hydrogen and oxygen by electrolysis, and then powers the car on the resulting energy. A display stand with rollers allows the car to operate in-place for proof of concept, or it can be released on a table or floor to roll under its own power. A booklet of 10 experiments challenges learners to calculate the efficiency of the solar cells and fuel cells using the included multimeter (requires two AA batteries), discover the effects of direct and indirect radiation, perform an Oxy-hydrogen test, and more. Includes all necessary parts, tools, and a lab manual (distilled water not included). Ages 10 and up. Boxed 17" L x 12" W x 4 1/4" D. (3 1/2 lbs.)
