Three-chamber microbial fuel cell with three GL14 connections per chamber and middle chamber. The chambers are connected via sealing rings, which prevent leaking when clamped. Steel clamps connect the side arm flanges safely together.

Each chamber has a volume of 100 ml, based on standard laboratory bottles with GL45 closure. The flanges allow a flexible connection depending on the test condition and can later be separated and connected to each other via membranes. The system can be adapted to customer requirements.

A reactor system consists of:

2 flanking chambers, 100 m
1 middle chamber, 100 ml
Top openings, threaded GL45
1 side arm / flange GL45 with groove per flanking chamber
2 side arms on the middle chamber
Flanking chamber with 3 ports with GL14 thread per side chamber for tubing connections
Middle chamber with 2 adapters with GL14 thread on the middle chamber for tubing connections
Accessories: screw caps with and without hole, septa, sealing rings, screw terminals

Port arrangements to the side chambers: 2 access to the side arm, with 1 at the bottom and 1 at the top. The 3rd port is at the top center at a 90 degree angle between the side arm and the top side port.

Arrangement of the port to the central chamber: to face each other, centered between the flanges, 1 port at the bottom and 1 port at the top.

A microbial fuel cell (MFC) or a biological fuel cell is a bioelectric system in which microorganisms convert their substrates (sugars, proteins, metals, etc.) into electricity. A bioelectric system consists of at least two electrodes, an anode and a cathode. The electrodes can be made of various electrode materials, e.g. from carbon cloth, carbon paper, graphite rod, etc. Microorganisms can grow in substrate solutions on electrodes to convert a large variety of organic materials into energy, water and carbon dioxide their natural systems. The microbes use only part of the energy they generate to process nutrients and sustain their lives. With MFC, the remaining energy can be used to generate electricity. MFC offer a wide range of applications, such as wastewater treatment and power generation, underwater energy needs, biosensors, power for implanted medical devices, etc. H cells are defined according to the shape of the cell. They can be used as a reactor and other electrochemical cells. Assembled H-cells have a volume of 100 ml on each side of the chamber. The compact design of the H-cell was particularly suitable for research and development to achieve initial results efficiently. It is suitable for the use of various substrates, such as basal medium, complex media and other growth media. Wastewater or organic liquids, natural seawater, etc. are also possible.
