An inverted rotating disk electrode reactor (IRDE) is constructed to facilitate the
study of electrochemically formed gas bubbles.
The hydrodynamic and mass
transfer characteristics of this new cell design are validated by means of an
electrochemical reaction with known characteristics, i.e.
the ferri/ferro cyanide
This validation is done both qualitatively and quantitatively.
The qualitative validation consists of comparing the entire polarization curve
obtained in the IRDE with the one obtained in the classical RDE set-up under the
same experimental conditions.
To quantitatively validate the cell another
approach was pursued.
A previously developed statistically founded method to
model an electrochemical system and to quantitatively determine its mass and
charge transfer parameters is used.
It is found that the mass and charge
characteristics in both configurations agree very well.
