The use of centrifugal fields in electrochemical energy conversion
Intense centrifugal fields can be exploited to increase the electrochemical reaction rates in energy conversion devices such as batteries and fuel cells to improve their overall performance characteristics. This paper describes how 'sin-enhanced natural circulation', created under high centrifugal acceleration, can be used as a means for promoting an increase in mass transfer and hence reaction rates in three-dimensional porous electrodes. Some relevant scaling laws and new theoretical insights are discussed to identify the main governing parameters in the design of centrifugal electrochemical energy-conversion systems. Recent findings obtained during the development and testing of a small prototype centrifugal zinc-air battery are presented to indicate possible trends and future prospects of this approach.
