AEM（Anion Exchange Membrane）

Our research focuses on the molecular design, precise synthesis, and industrial application of high-performance anion exchange membranes (AEMs) towards alkaline water electrolysis on the basis of bio-inspired principles. The AEMs can be integrated with transition metal-based catalysts and coupled with renewable energy sources, providing a new pathway to explore the economic efficiency and stability of hydrogen production. In addition, the developed AEMs can be also extended to carbon-neutral fields such as fuel cells and carbon dioxide resource utilization, which have been regarded as key factors for energy conversion and storage.

HER（Hydrogen Evolution Reaction）

Our research focuses on the redesign and scalable preparation of low-cost and high-performance transition metal-based HER catalysts in the AEM-WE for the purpose of overcoming the resource and cost limitations of traditional precious metal materials. The efficient and stable conversion of green electricity to green hydrogen can be promoted through the integration of HER catalysts with advanced AEMs and OER catalysts.

MEA（Membrane Electrode Assembly）

The membrane electrode assembly (MEA) is the core component of AEM-WE, which is composed of an orderly assembly of key materials including the OER catalyst, AEM, and HER catalyst. It establishes stable three-phase interfaces, provides sites for water-splitting reactions, catalyzes electrochemical processes, and separates the generated gaseous products. The performance of MEA directly determines the efficiency, lifespan, and cost of the whole electrolyzer. Therefore, in addition to the development of high-performance catalysts and membrane materials, multi-dimensional optimization including MEA configuration design, encapsulation assembly, and operational condition refinement is also essential for constructing a stable, efficient, and low-cost integrated system. This approach serves as a key technology to promote the commercial application of green hydrogen production.

Beyond

Through the coupling with renewable energy, the anion exchange membrane electrolyzers can serve as reactors to drive the oxidation and reduction of organic substrates for the production of high-value-added chemicals (such as furandicarboxylic acid, furandimethanol, NADH, etc.) by using water as both the oxygen and hydrogen source. This research focuses on the development of novel and highly active catalysts, as well as high-performance electrolyzer reactors those integrate the anion exchange membranes, aiming at establishing a practical and promising green electrochemical synthesis paradigm based on AEM electrolyzers.
