Electrochemically driven cooling

In this research topic, you will explore a new concept for a miniaturized electrochemically driven cooling system comprising an electrochemical cooling cell. Two mechanisms ensure effective heat dissipation: (1) endothermic redox reactions at the electrode/catholyte and electrode/anolyte interfaces, and (2) the advection of the electrolyte to transport heat within the electrolyte solution away from the hot surface. Both processes simultaneously contribute to dissipation of heat from the chip. However, Joule heating in the bulk of the electrode and electrolyte, as well as charge transfer resistance losses at the interfaces constitute a undesired source of heating. The main challenge will be overcoming deviations from the theoretical maximum cooling efficiency, linked to reaction activation energies and internal losses. As part of the research, a miniaturized cell with low internal and charge transfer resistance will be designed to minimize Joule heating.  The anolyte and catholyte will be selected for maximum redox driven heat transfer.
