Solid Oxide Fuel Cells (SOFCs) have been shown to generate power with a wide variety of hydrocarbon based fuels. The operation of SOFCs with alternative fuels is hindered by carbon deposition and sulfur poisoning. Here we analyze the performance and

Creation of new membrane materials for proton exchange membrane (PEM) fuel cells operating at elevated temperature and significantly reduced relative humidity (RH) is one of the major challenges in the implementation of the fuel cell technology. High

A new experimental electrochemical system was developed for measuring corrosion rates in high temperature dilute electrolyte solutions. The system was tested at temperatures and pressures up to 350 oC and 20 MPa. The low corrosion rates in the aqueou

Our approach for elevating the operational temperature of PEM fuel cells above 100 oC is to use inorganic particles inside a composite membrane. Inorganic components tend to enhance water retention at elevated temperatures and can reduce undesirable

Since the surface properties of solid oxides, such as zeta potential, surface charge density, and stoichiometry of surface complexes reflect the interfacial behavior of solid oxide particles, detailed surface studies can help to predict the performan

The lack of proton conductive polymeric membranes stable at high temperatures is one of the main issues impeding the development of DMFCs. The currently employed Nafion membranes are not suitable at temperatures abouve 100 degrees C due to a substant
