How does a fuel cell produce electricity? Rosalind, a chemical engineer, uses a model to show the process of fueling a car with hydrogen and using that hydrogen to power the model car. The STEM video provides an explanation of the chemical reactions that take place, both at the fueling station and in the fuel cells.
