My results showed the Salt Pond fuel cells had a moderate production of volts (0.015-0.020 V) produced. However, two of the 3 fuel cells died but started producing voltage again after a couple of days (Figures 1. and 2.). Salt River had a fuel cell that was dead from the start and never produced any voltage. Another Salt River fuel cell had the highest production of volts overall (0.94 V). The voltage for all fuel cells of both benthic substrates was still increasing after I concluded my experiment. This information tells me that the Salt Pond fuel cells are more reliable then the Salt River ones since they produced more consistent voltage. When the Salt Pond fuel cells “died” they started producing electricity again, while the Salt River fuel cell that died at the start never produced anything. The Salt River fuel cells are more unpredictable as well because the first cell produced moderately, the second did not produce at all, and the last one produced amazingly.
