Design of Microbial Fuel-Celled Power System

The world today is undoubtedly facing a serious energy crisis and energy demand in the world continues to increase at an unsustainable pace. Renewable and non-renewable sources of power generation are rapidly increasing but only few highly established and giant companies can afford these kinds of technology. This study aims to provide alternative power source to people who cannot afford paying high dues of electricity especially for local households where they can use a cheap, environmentally-friendly and lower cost of electric consumption such as using microbial fuel cell power source system. An alternative light source has been produced through the idea of a prototype development of a microbial fuel-celled power source system. The system is composed of an MFC power system with an anode and cathode chamber connected by a mediator. The power produced by the mfc goes directly to the external circuit composed of set of capacitors connected in parallel and is also connected to a 1.2VDC Ni-Cd rechargeable battery which is controlled by a mechanical switch. The prototype is made from plastic wares and is connected by a PVC pipe and sealed by vulcaseal for tight and secured output. The prototype is effective when it comes to providing DC power supply for lighting loads. More efficient power supply can be produced if the MFC will be used as a recharging component of rechargeable batteries.
