Abstract

Soil microbial fuel cells (SMFCs) are a promising cost-effective power source for on-demand electricity generation applications. So far, reported SMFC configurations are usually bulky and hard to setup. In this study, a low-cost portable plugged-type SMFC (PSMFC) was designed and fabricated for on-demand micropower generation. The PSMFC can be activated just by plugging into natural wet soil, which is easy to access in the natural condition. The PSMFC uses carbon-based electrodes for cost-effectiveness. After setting the PSMFC into the soil to activate, it started to produce electricity after 1 h and reached the power density of 7.3 mW/m² after 48 h. The proposed PSMFC can potentially generate electricity for remote sensors or soil sensing systems.

Key findings

  • PSMFC can be activated by plugging into natural wet soil
  • PSMFC produces electricity after 1 hour of activation
  • PSMFC has a power density of 7.3 mW/m² after 48 hours
