Zusammenfassung
Electrochemical reactions exhibit autosustained oscillatory states once the appropriate parameters are applied. As shown herein, the main impact of operating a reaction in an oscillatory state is the increased efficiency. The electroxidation of CO-containing hydrogen is analyzed because its oscillating mechanism mimics the oscillator known as hidden negative differential resistance (HNDR). With that, experimental results and the thermodynamic calculations of this contribution could be extended for other HNDR oscillators such as ethanol and methanol electroxidation. The enlarged efficiency results from a smaller chemical dissipation.
