[Membrane technology] Anion-Exchange membranes for Alkaline fuel cells 발표 (UNIST, 영어대본포함)

1. Introduction

Anion-exchange membranes (AEMs) have emerged as a crucial component in the development of alkaline fuel cells (AFCs), which are garnering increased attention due to their potential for clean energy applications. Alkaline fuel cells operate efficiently at moderate temperatures and utilize a simple reaction mechanism, making them a compelling choice for future energy systems. Unlike proton-exchange membrane fuel cells (PEMFCs), which require costly noble metals like platinum as catalysts and operate in acidic environments, AFCs utilize abundant and inexpensive alkaline solutions, reducing overall system costs. This fundamental shift in electrochemical design presents significant advantages in terms of material availability, operational stability, and cost-effectiveness. The advancement of AEM technology has been pivotal in improving the performance and reliability of alkaline fuel cells. Anion-exchange membranes are capable of conducting hydroxide ions (OH), which is
