The low-cost cathodes of titanium-nickel (Ti/Ni) and graphite felt-nickel (GF/Ni) are important to be evaluated as cathodes for MFCs. In this study, Ni particles are deposited onto the Ti and GF surface using a simple and low-cost electrodeposition technique. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to analyse the cathode surfaces. The electrodeposition of Ni onto GF appears more uniform without significant agglomeration compared with that onto Ti. This uniform deposition is perhaps the reason for a higher maximum power density (P-max), lower internal resistance (R-in) and higher Columbic efficiency (CE) for MFC with GF/Ni cathode (113.4 +/- 0.6 mW/m(2), 1264.4 Omega and 29.6%, respectively) than those measured with Ti/Ni cathode (110.7 +/- 8.0 mW/m(2), 3375.8 Omega and 23.7%, respectively). However, the performance of these cathodes remains lower compared with the GF/Pt cathode (140.0 mW/m(2), 845.7 Omega and 42.0%, respectively). Based on the preparation technique, material cost and performance, both Ti/Ni and GF/Ni cathodes can be considered as alternative to Pt catalyst for MFC application.
