In the single chamber air-cathode MFC (without PEM), why will the bacteria not grow on the electrode exposed to air ? Is it not easier to grow at a site that is readily exposed to oxygen ? So, If they do grow, would this not result in electron transfer at the intended cathode instead of at anode ? If this happens, will oxygen readily accept the electrons at the air exposed side resulting in zero potential difference across the electrodes ?
Hi Akshith, what material do you have in between the air and the electrode? Is it a gas permeable membrane?
Hi Mr. Barber, sorry for checking your reply so late.
There is no material between electrode and air. This model is like the one described in Dr. Logan's paper with comparison between air-cathode MFC with and without a PEM.
