title = "Effect of IEC and loading of cathode SPEEK binder on kinetic and transport properties of all-SPEEK MEAs",
abstract = "The choice of polyelectrolyte in the catalyst layer is an important consideration in the formation and efficacy of the triple phase boundary. It also influences the stability of the electrolyte/electrode interface for long term fuel cell performance. The polyelectrolyte composition in the electrode has to be optimum for higher Pt utilization and hence better MEA performance. MEAs with SPEEK (of different IECs) as binder in the electrode layer and SPEEK (IEC 1.75 meq/g) membrane were prepared by decal transfer. MEAs were tested at 80° C and 75\% RH. Steady state polarization curves were obtained with air and oxygen. Polarization data for MEAs with different binders in the electrode were analyzed to determine the relative contributions of the different sources of polarization, namely activation losses, membrane resistance losses, ohmic losses in the electrode, and mass transport losses in the GDL and electrode.",
