Fuel Cell Technology and Applications

Jacob from Make Science Fun demonstrates a DIY fuel cell kit from Horizon Educational. He explains the components, prepares the fuel cell, hydrates the membrane, and performs electrolysis to generate hydrogen and oxygen gas. The generated gas powers motors and lights, showcasing energy transformations. Jacob also builds a model car using the fuel cell, highlighting the potential for educational projects and competitions.
