Charge-transfer and transport phenomena

For industrial applications, other parameters such as ease of implementation and maintenance and investment cost guide the decision as to which electrode configuration will be used. These configurations will be described in the appropriate sections of this book. 

The extensive Butler-Volmer relation for charge transfer 

The electrode processes that are dealt with in this work relate to the transfer of electrons at an interface between a conductive material and an aqueous solution. Since it concerns a heterogeneous process, at least three steps can be distinguished  

Supply of reacting component from the dissolution phase (transport). 

Discharge of reaction product away from the electrode surface (transport)66.
