Study of Microbial Fuel Cell for Implantable Application

This study is focused on the production of low power density energy using a single chamber Microbial fuel cell (MFC). The potential, developed between the bacterial metabolic activity and electron acceptor, was separated by a membrane (perfluro sulphonic acid membrane in this case) manifesting bioelectricity generation. The achievable power output from MFCs can be tuned by modifying the system design, such as optimization of the Membrane Electrode Assembly (MEA) structure, cell operating conditions, and the choice of biocatalyst. The advantages for implantable application are biocompatibility and natural, safe and light, continuous power output, minimal invasiveness, long life cycle, easy to integrate electronics. Selection of the anode-cathode electrodes materials and structure is one of the critical challenges of MFC. Carbon and blends with graphene are used for developing the electrode diffusion structure. Microbial fuels were inoculated with MRS broth containing Lactobacillus Cesai Shirota. obtained Low powers of about 3.0 micro watts was obtained in the 5 cm2 cell was obtained.
