Advanced - For experienced high school and college classes; requires some technical skill.

• Investigate cellular respiration
• Explore an alternative fuel source
• See microbes in a new light

Use this high-quality fuel cell in an exciting cross-curricular lab that explores cellular respiration, electrical currents, microbiology, and the need for alternative fuels. The fuel cell uses the metabolic activity of ordinary baker’s yeast to create a small electric current; its design is based on original research done by Dr. Peter Bennetto, formerly of King’s College, London. Chemicals arrive dry, in premeasured amounts.

The Microbial Fuel Cell is also sold separately and includes 2 sets of neoprene gaskets, a cation-exchange membrane, and carbon fiber for electrodes. The cation-exchange membrane can be reused many times. Note: Sold only to high schools, universities, colleges, and businesses.
