New fuel cell system is the first of its kind
A team of scientists from the Iowa State University have, for the first time, developed a microbial fuel cell that is not reliant on external power to operate. The new fuel cell is the first of its kind and could have major implications for the fuel cell industry as a whole in the future. The energy system currently exists in a proof-of-concept stage, but has shown significant promise in its ability to generate electricity.
Microbial fuel cells could be viable energy systems for those interested in clean energy
A microbial fuel cell uses bacteria to break down chemical bonds and produce electrons. These electrons are then used to generate electricity. With past fuel cells, a “food” supply would need to continuously be fed into the system. If the flow of food stops, the bacteria no longer produce electrons. As such, microbial fuel cells would have to rely on external power sources in order to keep functioning. This problem has made these types of fuel cells somewhat unpopular compared to their hydrogen-powered counterparts.
