ChemBE Seminar Series: Yushan Yan

Description

Yushan Yan, the chair of Chemical and Biomolecular Engineering at the University of Delaware, will give a talk titled "Accelerating the Energy Transition: Green Hydrogen, Fuel Cells and Carbon Capture" for the Department of Chemical and Biomolecular Engineering.

This is a hybrid event. To attend virtually, use Zoom ID 919 5918 2879 with passcode 270887.

Abstract:

The transition to a low carbon economy to avoid the climate change requires green hydrogen, fuel cells, and carbon capture. Green hydrogen is necessary for the decarbonization of the sectors of our economy that are inaccessible by renewable electrons, such as ammonia synthesis. For low temperature electrolzyers for green hydrogen generation and fuel cells for transportation, polymer electrolytes play a central role in controlling their cost, performance, and durability, and consequently their economic viability. In this presentation, I will focus on our work on hydroxide exchange membrane electrolyzers (HEMELs) and fuel cells (HEMFCs) that do not require precious metal catalysts and expensive stack components. I will also show our recent work on carbon capture using hydroxide exchange membrane fuel cells.
