Effects of crosslinker length on anion exchange membrane fuel cells

Anion exchange membrane fuel cells (AEMFCs), which produce electricity using hydrogen, are considered an alternative to currently used proton exchange membrane fuel cells. However, AEMs have problems with stability in alkaline conditions, which can be overcome by crosslinking. But effects of crosslinker length on AEMFC performance are not well understood. Now, Korean scientists have elucidated such effects for oxygen-containing crosslinkers. Using an optimally long crosslinker, they produced a novel AEMFC with greater performance.
