Abstract
Magnetic resonance imaging (MRI) to measure the spatial distribution of the water content within a polymer electrolyte membrane (PEM) under fuel cell operation is described. By designing and building a fuel cell that can operate in an MRI system and making measurements during the cell operation, the water concentration gradient in the PEM and the overall water content decreased with an increase of the cell current. Furthermore, the water content in the anode side of the PEM decreased significantly within 200 s of the cell start-up, and this caused a similarly rapid decrease of the cell voltage.
