Nanoporous niobium phosphate (Nb-P) electrolyte membranes were prepared by dry pressing Nb-P nanoparticles for low temperature fuel cells. Highly dispersible Nb-P nanoparticles were synthesized by dispersing Nb-P precursor in furfuryl alcohol, which was polymerized to poly(furyfuryl alcohol) as a space-confinement additive during calcination. SEM, TEM and a range of spectroscopies were used to characterize Nb-P particles and membranes (discs). Nanoporous Nb-P membrane exhibited high proton conductivity (17.4mScm-1), low methanol permeability (1.1×10-7cm2s-1) whereas Nb-P membrane prepared from Nb-P particles synthesized without adding furfuryl alcohol had poor proton conductivity (0.341mScm-..View full abstract
