Scientists at Pennsylvania State University found a creative source for these carbohydrates, sugars in municipal wastewater. Using Clostridium sp. to produce hydrogen gas from sludge could change wastewater treatment plants into local power plants. The plants would utilize the hydrogen gas in fuel cells. Clostridium sp.
Hydrogen cell has a proton exchange membrane. According to the American history.edu, hydrogen cell enters into the fuel cell as anode from the hydrogen tank. Later it was ionized it carry a plus charge and negative charge produced current that is used for operating the device. Oxygen enters into the cell as cathode from air and pluck up an electron that is coming from hydrogen and combine with hydrogen produce water as a by-product. The fuel cell generates electricity as long as the supply of hydrogen and oxygen.
Figure 1 demonstrates the design of a microbial fuel cell.. Figure 1(Mercer): 1 shows the bacteria on the anode. 2. shows the electron flow from the anode and into the circuit. 5. shows the creation of new water The only way to make the fuel cells practical is if they can be scaled up and produce a larger amount of energy. The cost will also have to be balanced against the design to make the fuel cell a cost efficient way to generate power.
