The linked paper summary says "...we describe a bio-photovoltaic energy harvester system using photosynthetic microorganisms on an aluminium anode..."
How do they prevent the aluminum from oxidizing? Oxidized aluminum is an insulator, which should be a problem for a long lived battery?
I don't have access to the whole paper since it's behind a paywall.
