Water and ion transport in anion exchange membrane fuel cells

Abstract

Much of the work on Anion Exchange Membrane Fuel Cells (AEMFCs) in recent years has focused on the development of new catalysts and membranes. Though this work is important, it has overlooked mass transport in these systems, which is equally critical to achieving high performance. This chapter provides an overview of aspects related to AEMFC water management and carbonation upon exposure to carbon dioxide. managing both of these are needed in order to achieve high performing fuel cells.
