Electrochemical performances of SPSU/Zn,Al-heptamolibdate LDH hybrid membranes for proton exchange membrane fuel cells

摘要

Hydrogen and electronic crossover increased with decreasing relative humidity but they can be considered negligible. The composite membrane performed slightly better than sulfonated..poly.sulfone at higher current densities. The polarization curves at different relative humidity values showed that the humidity reduction did not significantly change the performance of the composite membrane. This membrane was capable of withstanding low moisture without affecting the performance of the cell.
