Penn State researchers combining two bacteria in a cellulose fuel cell
Researchers at Penn State University are developing a microbial fuel cell that consumes cellulose and generates electricity. They are doing this by combining two types of bacteria, one that can break down the cellulose into simpler sugars and ferment it and another that takes the fermented product and generates electricity. Unfortunately the two chamber design that is required to make this work results in very low power density currently at 150 mW per square meter. The team is looking for ways to improve on this.
