DOE Has Issued Request for Information Regarding Rotating Disk Electrode Diagnostics for PEMFC Electrocatalyst Screening

    May 21, 2013

    The U.S. Department of Energy's (DOE) Fuel Cell Technologies Office has issued a request for information (RFI) seeking feedback from interested stakeholders regarding the use of rotating disk electrode (RDE) experiments and best practices for experimental conditions for characterization of the activity and durability of proton exchange membrane fuel cell (PEMFC) oxygen reduction reaction (ORR) electrocatalysts.

    A review of recent literature shows that the determination of the ORR activity has numerous intricacies that have not been systemically cataloged, resulting in values for the activity of Pt/C that vary significantly. Next steps will be to establish standard procedures and measurement parameters for the RDE technique so that novel catalysts can be benchmarked for ORR activity versus an accepted Pt/C baseline for polymer electrolyte fuel cell applications. DOE is specifically interested in information on best practices/protocols to enable consistency in procedures and less variability in results from different laboratories.

    For details, see the RFI announcement DE-FOA-0000926 or email questions about the RFI to with "question" in the subject line. RFI responses must be received no later 5:00 p.m. (EDT) on July 12, 2013. This RFI is not a funding opportunity announcement; therefore, DOE is not accepting applications for funding regarding this topic at this time.
