The form of dispersed catalyst is especially suited for work with precious metals no such stringent limitation in the amount of material is needed with other less expensive materials. On the other hand, finely subdivided catalysts are necessary for use in the SPE (solid polymer electrolyte) technology [10, 318-320]. When dealing with dispersed catalysts, the degree of dispersion (particle size effect) and the nature...

Nafion (perfluorosulfonic acid) membranes are currently used in cells with a corrosive environment and high temperature. Many of these cells are designed with the solid polymer electrolyte (SPE) configuration. The merits of the solid polymer electrolyte technology will be discussed in the next section. 

The development of solid polymer electrolyte cells is being actively conducted at General Electric Co. (13) and at Brown Boveri Research Center, Baden, Switzerland (14). As the name implies, the solid polymer electrolyte technology uses a solid polymer sheet as the sole electrolyte in the cells. It also acts as the cell separator. The majority of the present applications use Nafion with a thickness of 10-12 mils (13). Selected physical and chemical properties of Nafion 120 membranes are given in Table I. The membrane is equilibrated in water to approximately 30% water content prior to fabrication into a cell assembly. The hydrated membrane is highly conductive to hydrogen ions. It has excellent mechanical strength, and it is very stable in many corrosive cell environments.
