Fuel cell, ethanol
This fuel cell kit with propeller contains a fuel cell that produces power from an ethanol solution of up to 15%. This makes it possible to investigate how the effect from the fuel cell changes with different ethanol solutions. There is also the option of making power outlets for other power consumption, e.g. bulbs or motor. A pH paper is included to examine changes in the pH value in the residual product from the energy process with the ethanol used.
