  • Title: The use of 1H NMR microscopy to study proton-exchange membrane fuel cells.
    Author: Feindel KW, Bergens SH, Wasylishen RE.
    Journal: Chemphyschem; 2006 Jan 16; 7(1):67-75. PubMed ID: 16345115.
    Abstract:
    To understand proton-exchange membrane fuel cells (PEMFCs) better, researchers have used several techniques to visualize their internal operation. This Concept outlines the advantages of using 1H NMR microscopy, that is, magnetic resonance imaging, to monitor the distribution of water in a working PEMFC. We describe what a PEMFC is, how it operates, and why monitoring water distribution in a fuel cell is important. We will focus on our experience in constructing PEMFCs, and demonstrate how 1H NMR microscopy is used to observe the water distribution throughout an operating hydrogen PEMFC. Research in this area is briefly reviewed, followed by some comments regarding challenges and anticipated future developments.
