The physiochemical properties of Nafion 115 and a composite Nafion 115/zirconium phosphate (∼25 wt.%) membranes are compared. The composite membrane takes up more water than Nafion at the same water activity. However, the proton conductivity of the composite membrane is slightly less than that for N

To achieve the maximum performance from a Direct Methanol Fuel Cell (DMFC), one must not only investigate the materials and configuration of the MEA layers, but also consider alternative cell geometries that produce a higher instantaneous power while occupying the same cell volume.

Composite silica/Nafion ® membranes were prepared using a tetraethylorthosilicate (TEOS) hydrolysis sol-gel reaction followed by solution casting. Physico-chemical properties of the composite membranes were characterized by TGA, XRD, FT-IR, SEM-EDX and water uptake. Membranes were investigated in di
