This fuel cell kit is a playful introduction to one of the most significant technologies of the 21st Century. With this kit you can build a model car that actually runs on hydrogen which you produce on-board by electrolyzing water. This kit is really a toy to be used at home rather than in a classroom. It includes a manual with experiments, but the structure of the manual makes them difficult to follow in a classroom setting. The difference between this kit and the Thames and Kosmos X7 is that this kit does include a solar panel or multimeter and the experiment manual in this kit is 94 pages rather than 16 pages.
