Abstract

Nafion® membranes were modified by in-situ sol-gel reactions of silicon alkoxides that create silicate nanoparticles. The purpose of this inorganic modification is to reduce fuel crossover in membranes for fuel cells. The hypothesis is that the particles will create diffusion obstacles for the gases thereby reducing fuel crossover. The MEAs prepared from the silicate-modified Nafion® membrane were subjected to open circuit voltage tests at 100°C and 25% relative humidity to assess the effect on fuel crossover and membrane performance. Initial studies suggest that these incorporated particles can reduce membrane performance deterioration.
