D5.1 - escription of developed ex-situ functional characterisation techniques (M15)

Abstract: The proton-exchange membrane fuel cell (PEMFC) is a promising lowtemperature fuel cell for CO2 neutral electrification of vehicles. However, marketability requires reduced stack cost and improved lifetime. One costly component is the gas diffusion layer (GDL). The task of reducing GDL cost requires measuring the important physical GDL properties, so that they can be optimised both in terms of cost and function. This report describes the development of measurement methods of physical GDL properties for convective transport, electrical bulk conductivity and contact resistance.
