- The proton exchange membrane (PEM) is the core component of the fuel cells because it works as a proton conductor, a gas separator, and the insulator of the electrodes. For proper working, the PEMs should always maintain enough hydration. If the PEM is working under low hydration condition, the reliability of the PEMFC system is enhanced due to minimizing a balance of plant. Many research groups have reported that nation and inorganic filler based composite membranes show increasing performance under insufficient hydration condition compared with the pristine Nafion1-2. We synthesized sulfonated silica and Nafion composite membrane, and it also showed good performance under low hydration condition3. In this study, we try to understand the relationship between the proton conductivity enhancement and morphological variation due to the composition with sulfonated silica by using atomic force microscopy (AFM).
