This work presents a simple production method for TiO2 reinforced Nafion membranes which are stable up to a 120o C operation temperature. The novel TiO2 reinforced membranes yield a maximum power 2.8 times higher than the highest power density for TiO2 reinforced membranes so far published in literature. The described membranes even exceed the maximum power density of a commercial Nafion HP membrane in an identical measurement setup at 100 o C and 120 o C. The membrane is manufactured by drop-casting a dispersion of Nafion and TiO2 nanoparticles onto both the anode and cathode gas diffusion electrodes.
