The simplest versions of these toys contain magnesium metal sheets. Sprinkle a few drops of saltwater into the car and it will run for hours without assistance. More advanced fuel cell cars, like the i-H2GO, come with all the pieces kids need to construct a hydrogen-powered car, then allow kids to connect the car to a smartphone, which acts as a wireless controller.
