Upcoming Webinar March 12: Testing Oxygen Reduction Reaction Activity with the Rotating Disc Electrode Technique

March 8, 2013

The Energy Department will present a live webinar on March 12, 2013, from 12:00 to 1:00 p.m. EDT, highlighting the use of the rotating disc electrode (RDE) technique to measure oxygen reduction reaction (ORR) activity in fuel cell applications. Attempts have been made 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. A review of recent literature shows that the determination of the ORR activity is plagued with intricacies that have not been systemically cataloged resulting in values for the mass activity of Pt/C that vary by a factor of as much as two. The webinar will address these issues, and introduce a tentative set of testing parameters to allow for RDE experiments to result in reproducible ORR activity and durability values.
