Wetlands are ecosystems rich in organic matter due to the high biomass of vegetation that characterize them. This organic matter could be used as a substrate in devices to generate electricity through Sediment Plant Microbial Fuel Cells (SPMFC). In this study we applied the SPMFC concept adapted to Typha domingensis Pers., a typical wetland plant. SPMFCs were constructed with glass cells and graphite electrodes under natural environmental conditions. Electrical current production was 47.9 ± 10.98 mA/m2 with 6.12 ± 2.53 mW/m2 power (data normalized to plant growth area). Trials were performed using an electrical motor (CEBEK 0.7V and 10 mA) which moved a cardboard propeller for 15 min intervals during 6 days.
