✦ Synopsis

Electrochemical processes may be used to form thermodynamic cycles in a variety of manners. In this paper, an electrochemical cell and fuel cell are combined to form a refrigeration cycle. Water is chosen as an example for the analysis in order to show ideal performance characteristics of such a cycle. Ideally, the system is close to Carnot performance. In actual systems, the electrolyser side of the system must be operated below neutral voltage levels in order to achieve a refrigeration e!ect. For the water-based system results presented, water mass #ow rates less than 6 kg per h are required per &ton' of refrigeration e!ect for the ideal system. The e!ects of operating temperatures on cycle e$ciency for the example system are also presented.

A natural enargite (Cu 3 AsS 4 ) electrode has been studied by cyclic voltammetry (CV) and XPS. Cyclic voltammetry was carried out in a preparation chamber filled with Ar gas and coupled to the spectrometer in order to analyse by XPS, quasi-in situ, the electrochemically modified electrode surface.
