The polymer membrane in the study is reinforced by raising hydrophilicity on structure due to incorporation with hydrophilic inorganic material. Due to the addition of hydrophilic functional groups, protons are easily appealed and transported through membrane. Therefore, electrochemical reaction in battery/fuel cell can take place at faster kinetic and thus be expected to perform with high cell efficiency. As a result, the inorganic-doped polymer membrane shows enhancement in physical properies such as water uptake, ion exchange capacity, and proton conductivity. To confirm improved properties and contribution of inorganic dopant, structural analyses are carried out using scanning electron microscopy, Fourier transform infrared spectroscopy, and thermo gravimetric analysis. The accomplishment of this work confirms the method for improving hydrocarbon membrane by inorganic/organic hybridizing preparation to make the electrolyte material more promising for battery/fuel cell application. |
