A Study Of Polymer Electrolyte Membranes And Associated Interfacial Systems Via Molecular Dynamics Simulations, Junwu Liu
Doctoral Dissertations
The development of novel polymer electrolyte membrane (PEM) materials which operate at high temperature (i.e. > 100˚C) and low humidity conditions and efficiently transport protons has been a major focus for PEM fuel cell technology. The motivation behind a high temperature PEM fuel cell is based on the fact that, at high temperature, the catalysts used in the fuel cell are more active and less susceptible to poisoning due to impurities in the feed stream. The challenge lies in the fact that as the temperature is increased, the membrane loses water and its ability to transport protons. The successful design and …

An Analysis Of Anaerobic Dual-Anode Chambered Microbial Fuel Cell (Mfc) Performance, Min Hea Kim
Masters Theses
Microbial Fuel Cell (MFC) technology utilizes bacterial growth in carbon-containing solutions to generate electricity or hydrogen. For the direct production of electricity, an MFC operates aerobically at the cathode and anaerobically at the anodes. The same basic design can be used with minor changes to produce hydrogen at the cathode by applying an additional overpotential and omitting oxygen from the cathode. In this configuration, the device is called an MEC (Microbial Electrolysis Cell). However, the term “MFC” is frequently used to describe both devices. The primary objectives of this study were to determine optimal operating conditions and to minimize the …
