Data for the paper: Pressure drop through platinized titanium porous electrodes for cerium-based redox flow batteries

Abstract

Data sets support: Luis F. Arenas, Carlos Ponce de Leon, Frank C. Walsh, Pressure drop through platinized titanium porous electrodes for cerium-based redox flow batteries. AIChE Journal, 2017.Abstract: The hydraulic pressure drop over porous electrodes used in redox flow batteries is linked to pumping costs and overall energy efficiency such that characterization of the hydraulic properties of porous electrodes relative to their electrochemical performance becomes a necessity during scale-up. In this work, the pressure drop at diverse Pt/Ti electrodes in a cerium-based redox battery is reported as a function of the mean linear electrolyte velocity and channel Reynolds number. Darcy’s friction factor and permeability are calculated. The electrochemical performance of the electrodes, expressed as the volumetric mass transport coefficient, , is given as a function pressure drop, allowing quantitative comparison vs. other electrode materials. In flow-by configuration, Pt/Ti felt combines high values with relatively high pressure drop, followed by Pt/Ti micromesh. Pt/Ti mesh and Pt/Ti plate plus turbulence promoters yielded significantly lower pressure drop but poorer electrochemical performance. Implications for cell and stack design are discussed.Description of data: Data for pressure drop through platinized titanium porous electrodes for cerium-based redox flow batteries. The data includes pressure drop, friction factor and permeability as function of mean electrolyte velocity and channel Reynolds number. The electrochemical performance as limiting current and volumetric mass transport coefficient is also provided and linked to the pressure drop.
