Graphite electrodes are the most commonly used electrodes for microbial fuel cells, though there are other materials, which are used for the electrode to allow a better conductivity, the most important idea is based on the size of these electrodes: the larger the surface of the anode and of the cathode in any situation, the greater the power density. Emerging nanomaterials such as graphene offer a high surface area and high electrical conductivity, which provides the opportunity to increase the power density in the cells. This article shows the characterization of a new electrode made with a conductive glue, graphene powder and silver paint.
