Batteries and fuel cells working group report
Electrochemical energy systems are dominated by interfacial phenomena. Catalysis, corrosion, electrical and ionic contact, and wetting behavior are critical to the performance of fuel cells and batteries. Accordingly, development of processing techniques to control these surface properties is important to successful commercialization of advanced batteries and fuel cells. Many of the surface processing issues are specific to a particular electrochemical system. Therefore, the working group focused on systems that are of specific interest to DOE/Conservation and Renewable Energy. These systems addressed were: Polymer Electrolyte Membrane (PEM) Fuel Cells, Direct Methanol Oxidation (DMO) Fuel Cells, and Lithium/Polymer Batteries. The approach used by the working group for each of these systems was to follow the current path through the system and to identify the principal interfaces. The function of each interface was specified together with its desired properties. The degree to which surface properties limit performance in present systems was rated. Finally, the surface processing needs associated with the performance limiting interfaces were identified. This report summarizes this information
