It depends, which fuel and oxidant do you use?
If they are, respectively, they were, respectively, acetate and oxygen, at 25 °C and neutral pH, it would be an interesting result.
Usually, an acete-feed anode give a voltage of -0.300 V vs. NHE (both OCV and in working conditions) and an air cathode, not biocatalyzed, give (OCV) 0,425 V vs. NHE and 0,300-0,200 V vs NHE (in working condition).
It would means that your Agar-Salt membrane has an internal electrical resistance similar to Nafion.
It would be interesting to know which type of architecture has your MFC, tubolar for continuous flow or bottle-like, for feed-batch mode?
