This models includes the design and provision of STL files for fabricating a miniature Air cathode Microbial Fuel Cell (MFC) using 3D printing technology. These components are intended for lab-scale bioenergy experiments, educational demonstrations, or prototyping.

Key 3D-Printed Components:

Anode:

Houses the anaerobic bacteria (e.g., E. coli, Shewanella)

Designed to hold liquid substrate with proper sealing features

Air-Cathode

Contains the oxidant (e.g., air, KMnO₄, ferricyanide solution)

Electrode Holders

Slots for fixing carbon felt, graphite rods, or metal mesh electrodes

Designed to ensure secure electrical contacts

Top/Bottom Lids or Caps

Leak-proof sealing

May include ports for tubing, pH/ORP sensors, or syringes

Assemble with the Nuts and Bolts

Note: The full details will be published soon…
