Exciting models are built around the topics of generating, storing and using electricity from natural energy sources, which move through wind, water or sun and convey the applied technology in a playful way. In this way, an understanding of the forms of energy that will be so important in the future is awakened. The H2 Fuel Cell Car construction kit (art. no. 559880) is an ideal addition. With this extension kit, further models can be built and operated with a fuel cell.
