Use this kit to construct a hydrogen fuel cell car and teach the principles of fuel cell technology. Explore how the PEM (Proton Exchange Membrane) fuel cell converts the chemical energy of hydrogen and oxygen into electrical energy to power the motor. Once constructed the car uses a steering mechanism to drive around obstacles. The 14 page user manual provides background information into fuel cell technology and full assembly instructions.Contents:Reversible PEM fuel cellCar chassis and wheelsElectric motorLED lightsWater vesselsGas collectorsConnector cablesSyringeBattery pack with connecting leads (2 x AA batteries required)User manual
