Abstract
The purpose of this project is the synthesis and characterization of proton conductors such as cesium hydrogen sutfate (CsHSO4) and hydrogen titanate (H2Ti3O7.nH2O), aiming at the preparation of Nafion based composite electrolytes for direct ethanol fuel cell application (DEFC) at intermediate temperature (T > 130 ºC). The development of new proton conductors is considered a crucial st…
