To ensure maximum performance using the least amount of catalyst possible, it is important to carefully formulate catalytic inks for fuel cells and other applications. One key to maximizing performance is the characterization, optimization, and control of the catalytic powder during synthesis, when received, and during dispersion. This talk will present the analysis of powders typically used in proton exchange membrane fuel cells (PEMFC), particularly nanocrystalline Pt-based catalyst on porous carbon support particles. Non-destructive characterization techniques employing large sampling statistics, such as X-ray fluorescence (XRF), X-ray diffraction (XRD), and laser diffraction, will be the focus of this talk. First, we will briefly review the fundamental principles of each technique. Right after, we will discuss their application in characterizing catalytic powders for inks.
