[Analysis Case] Evaluation of Particle Size and Composition of Catalyst Materials using TEM and EDX

Evaluation of catalyst particles using STEM-EDX.

The electrodes of fuel cells are supported by Pt particles or Pt alloy (such as PtRu) particles as catalysts on carbon. Due to the fine structure of these catalyst particles, which are on the order of a few nanometers, SEM and TEM analyses are used for morphological observation and compositional analysis. In addition to evaluations in the initial state, degradation after current application has been reported, including modulation of alloy composition, leaching of Ru, and an increase in the diameter of catalyst particles; HAADF observation and high-resolution EDX analysis are very effective for these evaluations. Furthermore, multi-field observation and analysis enable the assessment of particle size and compositional distribution.
