    Non-Destructive Characterization of Catalyst Coated Membranes for Fuel Cells

    Spectroscopic techniques are powerful non-destructive tools to monitor Nafion membranes, catalytic coatings, and other components of a membrane electrode assembly during production of proton exchange membrane fuel cells (PEMFC). This presentation will discuss X-ray diffraction, X-ray fluorescence, and near-infrared spectroscopy techniques that can be used for materials characterization in development and production. Applications measuring nanocatalyst size, nanocatalyst loading, membrane hydration, and more will be provided as examples.

    This webinar will focus on the following key topics:

    • Proton-exchange membrane fuel cell
    • X-ray diffraction
    • X-ray fluorescence
    • Near infrared spectroscopy
    • At-line characterization

    Adiabatic Calorimetry for Performance and Safety Testing of Li-Ion Batteries

    This presentation describes how Accelerating Rate Calorimetry (ARC®) is the adiabatic method of choice to carry out performance and safety testing on Li-ion batteries. This technique is widely used within the industry to understand the thermal characteristics of cells.

    The theoretical background of the technique is described, with recommendations made across different testing types. Examples are shown across multiple form factors, from coin cells up to small modules.

    Test methods discussed include decomposition tests, nail penetration, overcharge, short circuit, infrared, optical, gas generation and analysis, heat capacity and cycling.

    This webinar will focus on the following key topics:

    • Principle of adiabatic calorimetry for batteries
    • Advantages of this method
    • Discussion of applications and results
    • Recommended testing practices
