Abstract
Recently, various steps have been taken to utilize and develop renewable and sustainable form of energies due to the negative impact and dire limitation over continuous dependency on fossil fuel. This paper presents the effects of aluminium mesh on the performance of a MFC. Aluminium mesh with rectangular shape was used as the electrode and experiments were conducted with respect to various types of resistors. The amount of voltages and power density generated were determined. It was found that the increase in bacterial activities resulted in the increment of oxygen supply, therefore, the voltage generated also increased. In addition, the longevity of bacterial activity is dependent on the amount of catalyst. Moreover, it was observed that the performance of aluminium mesh electrode was smaller than that of graphite electrode.
Highlights
The Microbial Fuel Cells (MFC) is a sustainable and renewable fuel cell where the system utilizes oxidation reactions to produce electricity by making via chemical energy [1, 2]
Typical synthetics exogenous mediators consist of metal organics and dyes such as Fe (III) EDTA, methylene Blue (MB) and Neutral Red (NR), these mediators are cannot be used for MFC
The objective of this paper is to investigate the influence of aluminium electrode on the performance of Microbial Fuel Cell (MFC)
Summary
The Microbial Fuel Cells (MFC) is a sustainable and renewable fuel cell where the system utilizes oxidation reactions to produce electricity by making via chemical energy [1, 2]. Organic fuel generating protons are oxidized by microbes and move across the membrane to the cathode. The mediators move from cathode to the anode via the membrane to release electrons in order to get oxidized again in the anode compartment. This action increases the rate of transfer of electrons which eventually rises the power output. On the surface of the anode, the microbes produce a biofilm where electrons are transferred through the membrane via conductance (11 ). Biofilms are formed which are essential for the electron transfer between the electrodes and microbes. The objective of this paper is to investigate the influence of aluminium electrode on the performance of Microbial Fuel Cell (MFC)
