Discover the future of bio-fuel cell technology! This device silently demonstrates how energy can be created from ethanol without combustion—and works, nonstop, for hours! Many fuel cells use hydrogen or methanol as fuel, but this fuel cell converts ethanol directly into electricity. After experiencing the initial demonstration, students can be challenged to explore polarity by reversing the wires or measure the pH of the ethanol as it is used up, and then to take it a step further they can determine the chemical reaction taking place in the fuel cell. Many inquiry opportunities include investigating questions such as how would the process be affected by temperature or does the concentration of the ethanol impact the amount of electricity produced? Kit includes a renewable energy manual, experiment guide, and all the materials required, except the ethanol, to complete the experiment.
