摘要: Abstract A novel composite polymer membrane based on poly(vinyl alcohol)/hydroxyapatite (PVA/HAP) was successfully prepared by a solution casting method. The characteristic properties of the PVA/HAP membranes were examined thermal gravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), micro-Raman spectroscopy and AC impedance An air-breathing DMFC, comprised an air cathode electrode with MnO 2 /BP2000 carbon inks Ni-foam, anode PtRu black Ti-mesh, membrane, assembled studied. It found that this alkaline DMFC showed improved electrochemical performance at ambient temperature pressure; maximum peak power density in 8 M KOH + 2 M CH 3 OH is about 11.48 mW cm −2 . From application point view, these show high potential for applications.
