Catalytic inks are key components when balancing cost, performance, and durability of proton exchange membrane fuel cells (PEMFC’s). Scaling up PEMFC production requires careful control of the ink to produce uniform electrode layers that use as little precious metal catalyst as possible. Particle size and dispersion critically impact the behavior of the ink and the resulting performance of the electrode layers. X-ray diffraction, laser diffraction, dynamic light scattering, and X-ray fluorescence are characterization techniques with proven ability to scale-up in support of mass production that, when combined, provide a comprehensive overview of the particles in catalytic ink mixtures.
This webinar will focus on the following key topics:
- X-Ray Diffraction
- Laser Diffraction
- X-Ray Fluorescence
- Dynamic Light Scattering
These techniques each probe a different size regime and, when combined, provide a comprehensive overview of the particles in the catalytic ink mixture.

Scott A Speakman – Principal Scientist at Malvern Panalytical
Scott A Speakman obtained his Ph.D. studying fuel cell materials at Alfred University. He completed a post-doctoral appointment at Oak Ridge National Lab, splitting time between supporting the High Temperature Materials Lab user program and researching fuel cell materials in EERE and FE programs. Scott then managed the X-ray Shared Experimental Facility at MIT for 8 years before joining Malvern Panalytical as a principal scientist. Scott A Speakman is a Fellow of the International Center for Diffraction Data and recipient of a 2013 Infinite Mile Award for exceptional service to MIT.
