Abstract
Fuel cell cathode ion exchange membranes were analyzed using small angles neutron scattering (SANS). SANS data helped to draw a clear picture of the morphology of membrane electrode assembly (MEA) electrodes. Addition of Nafion to the MEA decreased the gyration radius to 48Å, while the power law decreased to 3.19. These two parameters showed that the addition of Nafion and the application of high pressure help to attach smaller particles to each other in the second layer. The Modified Guinier plot at low Q levels determined the porosity of the materials.
