The most widely used polymer membrane for DAFCs is Nafion because it exhibits superior proton conductivity and excellent mechanical properties and chemical stability. However, Nafion membranes for DAFCs are expensive, have limited device lifetimes due to chemical and mechanical degradation, and have higher fuel crossovers through the membrane. Typically, to improve Nafion membranes, many researchers have modified Nafion membranes by modifying the Nafion matrix with organic or inorganic materials with different structures, sizes and compositions, modification techniques or multilayered systems in order to improve the physical properties of Nafion. In our works, we modified the Nafion with various fillers, such as Fe3O4-SGO, CeO2-ACNT and CeO2-TiC, which significantly used to address the limitations associated with commercial Nafion membranes. |
