中文摘要	We propose self-humidifying polymer electrolyte membranes with highly dispersed nanometer-sized Titanium dioxides for proton exchange membrane fuel cells operated. with dry H-2 and O-2. The nanosized TiO2 particles that have hygroscopic property are expected to adsorb the water produced from the cathode reaction and to release the water once the proton exchange membrane needs water. The preparation technology of nano-TiO2 particles in a commercial Nafion 112 membrane via novel in situ sol-gel reactions was developed, resulting in a semitransparent membrane with uniform distribution of TiO2 in the proton exchange membrane. It is found that Proton conductivity increases observably by dispersing 3 wt % nano-TiO2 in the Proton exchange membrane at low humidity condition, and the newly prepared TiO2-PEM improve the self-humidifying performance of Proton exchange membrane fuel cell.
