Earth has limited amount of energy. Currently most types of energy being consumed are not renewable and alternate renewable energy sources are desperate in near future. Microbial fuel cells use chemical reaction to produce electrical energy from waste using bacteria and substrate. It indicates the development of microbial fuel cell can obtain the goal mentioned above, alternate renewable energy, as well as waste disposal issue in our community. This project starts from building microbial fuel cells using organic substrate containing bacteria from the community such as Mosquito creek (fresh water), Deep cove (salt water) and Rocky point at Port Moody (salt water). Other materials for the fuel cell assembly are also readily accessible. Cell voltage data generated from Mosquito creek sample showed stable long-term performance. This fuel cell created around 380 mV during 18 days of experiment. It also performed better then the other fuel cells with ocean sediment. The long-term performance was hypothesized to be stable and well supported by the experimental data. However the performance difference between creek sediment sample and ocean sediment sample was not predicted in the hypothesis.
