The objective of the research study is to investigate and develop a next generation of high temperature proton exchange membrane fuel cells (PEMFCs).
The state-of-the-art electrolyte (Nafion (R)) has been modified in a variety of different ways and studied within a PEMFC. These modifications included varying the electrolyte's thickness and acid content to understand their role in water management, and doping the electrolyte with various hydrating inorganic compounds. These inorganic compounds consist of silicon oxide via sol-gel impregnation, silica particles, alumina particles, titania particles and aluminosilicate particles. By studying these different metal oxides, a theory can be developed based on the dopent's particle size, surface area, and pKa. All methods of membrane preparation produced a uniform, even distribution of the dopants within the nanopores of the electrolyte.
The goal of this research is the development of membranes for PEMFCs that can operate above 100°C.
