About the Lab
Professor Young Moo Lee's research lab specializes in the design and development of advanced polymeric materials for clean energy and separation technologies. The lab focuses on creating durable, high-performance anion exchange membranes and ionomers for low-cost fuel cells, with an emphasis on enhancing conductivity, mechanical strength, and long-term stability under harsh alkaline conditions. Key research directions include molecular engineering of polymers with tailored free-volume microstructures and the incorporation of aliphatic/alicyclic or aryl-ether-free architectures to improve durability and transport properties. The lab also explores applications in ion exchange membranes for energy conversion, gas separation, and sustainable materials.

15Within a polymer film, free-volume elements such as pores and channels typically have a wide range of sizes and topologies. This broad range of free-volume element sizes compromises a polymer's ability to perform molecular separations. We demonstrated free-volume structures in dense vitreous polymers that enable outstanding molecular and ionic transport and separation performance that surpasses the limits of conventional polymers. The unusual microstructure in these materials can be systematical
Abstract Low-cost anion exchange membrane fuel cells have been investigated as a promising alternative to proton exchange membrane fuel cells for the last decade. The major barriers to the viability of anion exchange membrane fuel cells are their unsatisfactory key components—anion exchange ionomers and membranes. Here, we present a series of durable poly(fluorenyl aryl piperidinium) ionomers and membranes where the membranes possess high OH − conductivity of 208 mS cm −1 at 80 °C, low H 2 perme
Anion exchange membrane fuel cells (AEMFCs) have attracted great interest as a low-cost fuel cell technology for clean energy conversion and utilization for the future. AEMFCs have been considered the most promising succedaneum to proton exchange membrane fuel cells (PEMFCs) for addressing the cost issues associated with PEMFCs due to utilizing non-platinum group metals as electrocatalysts under alkaline conditions (such as Ag, Ni, and Co). Herein, we focus on a critical topic of AEMFCs—-anion-e
Poly(fluorenyl- co -aryl piperidinium)-based AEMWEs reach outstanding current density values of 7.68 A cm −2 at 2.0 V with a cell durability of 1000 h.
<p>Aliphatic/alicyclic (Al)-containing polyimides (PIs), including fully-Al-PIs and partially-Al-PIs, are widely employed in electric, electronics, optical materials, and other advanced material fields. Examples include high speed multiplayer printed wiring boards, alignment films for liquid-crystal displays, fuel cells, batteries, gas separation membranes, pervaporation membranes, biomedical applications, and composites/hybrid materials. In the past decades, research has focused on the sy
Abstract Aryl‐ether‐free anion‐exchange ionomers (AEIs) and membranes (AEMs) have become an important benchmark to address the insufficient durability and power‐density issues associated with AEM fuel cells (AEMFCs). Here, we present aliphatic chain‐containing poly(diphenyl‐terphenyl piperidinium) (PDTP) copolymers to reduce the phenyl content and adsorption of AEIs and to increase the mechanical properties of AEMs. Specifically, PDTP AEMs possess excellent mechanical properties (storage modulus
