Mathematical modeling and experimental validation of thin low platinum content and functionally graded cathode catalyst layers
DownloadFall 2014
Low catalyst content remains a key requirement for the commercialization of polymer electrolyte fuel cells (PEFCs) into the energy, transportation, and material handling sectors. Understanding the fundamental phenomena reducing fuel cell performance at various stages of operation play a major...

Realtime Machine Learning based In-Cycle Control of Homogeneous Charge Compression Ignition
DownloadSpring 2023
Homogeneous Charge Compression Ignition (HCCI) has the potential to significantly reduce engine out oxides of nitrogen NOx emissions, while maintaining a high fuel efficiency compared to existing lean-burn spark ignition engines. HCCI is characterized by compression induced autoignition of a lean...
