    Applications and Software

    A RRDE system uses two potentiostats or a bipotentiostat to separately polarize a Ring electrode and a Disk electrode. These two electrodes are co-mounted on a specially designed electrode tip. Fluid flow created by the rotation of this tip in electrolyte causes mass-transport of the products from electrochemical reaction at the inner disk electrode to be measured by outter ring electrode. This study allows investigation of electrochemical reaction paths (mechanisms) common to fuel cell catalyst evaluations.

    A RDE system uses a single potentiostat to polarize a Disk electrode. Rotation of this disk electrode encourages mass-transport of ions in solution to the electrode surface. This increased flux benefits physical electrochemistry applications, such electroplating and fundamental research.

    A RCE system uses a larger area electrode that is a different form. This is common configuration for studying velocity-sensitive electrochemical corrosion such as in an oil and gas pipeline.
