Hello,
I am working on double-chamber micro-MFCs. The OCV of the MFCs is really low, I saw max 30mV or near that value. How could I increase OCV? Will increasing the concentration of ferrocyanide is going to help?
Volume of each chamber is 350 microliter
I am using mix bacteria culture.
Also I used Nafion 211 as proton exchange membrane.
Thanks in advance ..
I recommend you this paper: "On the staking of miniaturized air-breathing microbial fuel cells": https://www.sciencedirect.com/science/article/pii/S0306261918315332
Personally I don't like the idea of placing microbial fuel cells in series. If you have one bad cell this will severely hamper the performance of the stack.
In my mind for practical applications it makes more sense to increase the overall current of the system by increasing the cell area/volume or by connecting cells in parallel.
When you connect a microbial fuel cell to an electronic load you will typically require the use of a step-up convertor to boost the voltage. The losses here are typically lower than the losses associated with connecting in series.

Hello, Jules Lloyd Hammond and Szymon Potrykus
Thank you for the answers. But what I want to know is `how can I increase the OCV of individual MFC?`
