摘要/Abstract

摘要： The structure and proton conducting mechanism of solid polymer electrolyte (SPE) are
described. Since the conductivity of electrolyte is important in SPE electrochemical cell
research and development, we investigate quantitatively the conductivity of Nafion membrane
and its dependence on temperature and relative humidity. Ex perimental results show that
the conductivity of Nafion membrane increases with temperature and relative humidity. We
also reports on the preparation and development of SPE membrane electrode with the emphasis
on the mix ture pressing method and impregnation-reduction process to prepare SPE composite
electrode assemblies and their application to electrochemical sensors. We also investigate
and fabricate a potentiometric electrochemical sensor of hydrogen and ethylene to measure
the hydrogen and ethylene partial pressure.
