Title

Effect Of Spray Parameters On Electrode Surface And Performance

Abstract

PEM fuel cell electrode performance is shown to be influenced by catalyst ink application methods in a spray-type setup. As the spray parameters are varied, diffusion resistance changes significantly. SEM images reveal particles of ionomer and catalyst are formed with different sizes. Larger particles are formed when the ink has a greater amount of solvent evaporation between the gun and the membrane. These particles appear to be connected to the diffusion resistance of the electrode, with a greater number of particles leading to a lower diffusion resistance. ©The Electrochemical Society.
