Action Potential Driven Microbial Fuel Cell Design

[Shambo Hore]

Hello.

Many Organism Flux out Cation (i.e Na+) from their intracellular compartment to extracellular space. I found most of all Microbial Fuel Cell ( MFC ) run by proton produced by organisms. I am looking for new method and system to establish a fuel cell that can generate electricity by trapping the ions produce by action potential of a organism.

I am seeking for help and guide.

Thank you.

Innovative idea! I'm not immediately confident that it would make a convenient power source, but I know a lot less about energy cells than about action potentials (APs).

One thing to know is that the actual bursts of Na/K exchange constituting the voltage spike of the AP are passive transport, allowed by a chain-reaction discharge of a higher-energy state maintained by continuous active transport of ions across the membrance at the expenditure of ATP. Unlike with proton pumps, an equal charge of the intracellular and extracellular fluids is maintained throughout the whole process. It is only the membrane itself, acting akin to a capacitor, across which the voltage changes due to controlled changes in its permeability for individual ion types for which concentration gradients are maintained as part of the charged-up resting state. AFAIR, there's no transport proteins involved that are built to expend ATP to transport ions against a voltage gradient, like proton pumps do.

Do you have some way of working with that?

Good luck,
Raza

 Hello Raza.

I was fascinating with Electric Ell which led me to more curious to generate electricity by Biologically.
I have studding and try to design a concept hypothesis for power generation by biologically. In this state i am seeking
method for generate electricity by trapping the cation, efllux by organism, instead of proton. I think the cation trapping
concept will more efficient than conventional proton trapping Microbial Fuel Cell.
Hence, there i found no such effective method for biologically produce cation driven power generation.
Here i think Na+ battery https://en.wikipedia.org/wiki/Sodium-ion_battery  technology can lead this idea some how. In this strategy, organisms may immobilized on anodic substrate. Therefore organisms may act like cathode, from where the ion will release to anode surface.

I am looking for more information to develop this method.
