... for application as membrane separators in microbial fuel cells. The composite membranes are made by immersing Nafion-112 membranes in a solution containing aniline for different immersion times. The presence of polyaniline and sulfonic functional groups in the composite membranes is confirmed by means of Fourier...

.... In this research, two new membranes (Nafion 211 and Nx-424), along with well-known Nafion 117 and 112 were studied as electrolytes in the direct methanol fuel cells (DMFC). The Nafion 211 is the thinnest and latest membrane of Nafion series products and Nx-424 is a Nafion membrane with polytetrafluoroethylene...

... conductivity loss due to a not full hydration of the membrane. For this reason a study on the modification of perfluorosulphonic membranes (like Nafion) was carried out by introducing different percentages of inorganic oxides (like SiO 2 , ZrO 2 ) in the polymer matrix. These compounds have the function...

... lowers the degree of methanol crossover, on the other hand, the ohmic resistance increases simultaneously. Therefore, the cell performance using Nafion 117 as membrane is lower than that of Nafion 112. In addition, the performance of the MEA made in our laboratory is higher than the commercial product...
