Materials Characterization
Materials Compression, Resistivity and Permeability Tester
  • Used to measure thickness, through-plane resistivity, and in-plane permeability of materials such as membranes, carbon fiber substrate, gas diffusion layers (GDL) or entire electrode assemblies (MEAs) while under automatically variable compression force. Intuitive user interface and X-Cue automation language allows for the creation of dynamic and complex testing profiles, completely unattended.
Allows researchers to replicate the conditions that materials will experience while under compression in a fuel cell, flow battery, or electrolyser stack.
