2P-490 : Synthesis and Investigation of Anion Exchange Materials for Use in Anion Exchange Membrane Fuel Cell

Fuel cell, anion exchange membrane fuel cell (AEMFC) in particular, has recently received great attention as power generation device. AEMFC enhanced oxygen reduction catalysis, allowing the use of less expensive, Pt-free or precious group metal (PGM)-free catalysts. As the core component in AEMFC, anion exchange material must demonstrate the following conditions; first, good hydroxide ion conductivity at desired operation conditions. second, stable dimensional change. finally, good chemical stability under high alkaline environment. Our group synthesized polymers that meet the above conditions, successively. In particular, alkaline stability, ion exchange capacity and ion conductivity of AEMs were measured, and also tested single cell performance.
