dc.description.abstract | The goal of this work was the synthesis and characterization of agar membranes for microbial fuel cells applications. Three sets of membranes were synthesized. For a first set of membranes (2, 4, 6, and 8 wt% agar concentration), both proton conductivity (σ) and O2 permeability (OP) increased as a function of agar concentration, up to 4 wt% agar. Beyond this concentration, the σ levelled-off at 2.43 mS cm−1 and OP increased. A second one set was obtaining by mixing 2, 4, 6, and 8 wt% concentrations of agar with KCl 10 wt%. Both σ and OP increased as a function of increased agar concentration; nevertheless, the presence of KCl slightly affected in a negative way the OP. For the last set, agar concentration was fixed at 2 wt%, while KCl concentration was increased to 2, 4, 6, 8, and 10 wt%. The σ did not significantly increase with salt concentration and the worst values of OP were observed. It was thus confirmed that agar concentration plays a significant role in the increase of σ, but KCl does not improve membrane performance. Moreover, the agar membranes cost is two orders of magnitude lower than Nafion® 117. Therefore, the best membranes were those produced solely with agar. | ca_CA |
