In Situ Measurement of Ionomer Water Content and Liquid Water Saturation in Fuel Cell Catalyst Layers by High-Resolution Small-Angle Neutron Scattering

In fuel cell catalyst layers (CLs), the ionomer plays roles as a binder and proton conductor. The ionomer requires hydration for enabling proton transport; however, the accumulation of excess liquid water in CL pores hinders oxygen diffusion. Therefore, a key to the improvement of CLs is understandi...
