Abstract

In recent years; as a novel mode of converting organic matter into bioelectricity; Microbial fuel cells (MFCs) have gained significant attention. Among effective parameters in MFCs; substrate type and concentration play major role on MFC performance. In this study; a dual chamber MFC was used with a wide range of fructose concentrations: 10; 20 30 and 40 g/l. The MFC was inoculated with Saccharomyces cerevisiae as biocatalyst. A100µm of neutral red as mediator and also 100µm ferricyanide as oxidizer added to anode and cathode chambers; respectively. The MFC generated an open circuit voltage (OCV) of 690; 768; 548 and 507 mV with concentration of fructose from 10 to 40 g.l-1; respectively. Maximum power density of 32.16; 23.7; 18.9 and 10.47 were obtained with substrate concentration of 10 to 40 g.l-1; respectively. The maximum value of OCV and power density obtained with 10g.l-1 of carbohydrate. To investigate resistance effect on MFC performance; for each substrate concentration data acquisition system was set at optimum value for the resistance w
