Project Goals and Description:
This project aims to investigate low temperature fuel cells and electrolyzers, focusing on understanding the catalyst layer composition. The study will use X-ray photoelectron spectroscopy, a powerful technique for analyzing the elemental and chemical composition of the surface of the catalyst layer. The research will focus on changes in the surface speciation of the catalyst, support, and ionomer by comparing the catalyst layers made with different catalysts and exposed to different processing conditions or degradation stressors.
