Single-Cell Design

A single-cell EFC can be designed as a system with an anode and cathode compartment that is akin to conventional electrochemical power sources or downsized to microfluidic devices. Both concepts will be discussed herein as they offer distinct opportunities in future development. Applications with extremely low power demand that require cheap and disposable power supplies are addressed by micro-fluidic-type EFCs. Higher power demand applications and more robust systems, with potentially replaceable electrodes, are more amenable to compartment EFC designs. A further area of development is the fabrication of implantable medical devices, in which design constraints can be addressed by merging both microfluidic and compartment-type EFCs.

In Part Two, the reader is provided with practical examples of how the general equations defined in part one can be simplified/adapted to specific cases. The examples cover the most widely employed single cell designs, for steady-state and dynamic conditions, and evolve towards stack and system modehng. Finally, Chapter 10 introduces the reader to the problem of mechanical stresses in SOFC, and shows an approach for modeling mechanical stresses induced by the operating conditions. 

The single cell design employs an outer compartment which contains the working and reference electrodes and an inner compartment which contains the auxiliary electrode. The secondary compartment hangs into the working compartment and makes solution contact through a porous glass frit. 

Ideally an optical cell should be designed specifically for one experiment. This is because the experimental conditions in optics involve so many variable parameters that no single cell design will provide the optimal conditions for different experiments. Among these parameters, the most important are ...
