Project Goals and Description:
This project aims to investigate low temperature fuel cells, focusing on understanding the mechanisms of catalyst layer degradation. The study will use Transmission Electron Microscopy, a powerful technique for analyzing the catalyst layers. The research will focus on changes in the catalyst including nanoparticle size, distribution and density, morphology of support and distribution of ionomer. The catalyst layers will be investigated as a function of degradation stressors.
