The tubular plant microbial fuel cell was designed to increase the feasibility of this technology. To test the new setup two anode materials were investigated, namely a graphite felt and graphite granules. The average power output based on membrane area was 10?mW?m^?2 for felt, and 12?mW?m^?2 for graphite granules. The corresponding mass and volume power densities for the felt were 15 and 69 times greater than for the granules. This showed that a decrease in the use of anode electrode material is possible while achieving comparable power outputs per square meter of membrane. These findings make future applications of the plant microbial fuel cell technology more feasible due to costs reduction per kWh. Furthermore, this PMFC design could be likely applied into soils without the need to excavate the topsoil.
