Our society is currently confrontating with air pollution, global warming and depletion of the oil resources. These concerns can be alleviated by improved efficiency of power generation and distribution using electrochemical devices such as Fuel cells and Batteries. Alternative Powertrain Research Lab (APRL) led by Dr. Choe creates a research program that addresses fundamental understanding in electrochemical, thermal, and mechanical mechanism of the devices along with degradation by developing high resolution multi-physics and multiscale models. Innovative experimental equipment and validation methods are developed and used to verify the behaviors of the devices. Based on the understanding of the mechanisms, new application solutions for integrated systems are developed in conjunction with advanced controls that substantially improve efficiency, safety, and durability of the systems.
