Generating Hydrogen on Demand by Splitting Water with Al Rich Alloys

Woodall J.M., Ziebarth J., Allen J. Jeon C.R., Choi G., Purdue University, US

Our group has been pioneering the production of on-demand hydrogen using aluminum-gallium alloys to split water into hydrogen, heat, and alumina. Recently, we have found that we can split water on demand using solid alloys [...]

Carbon Aerogel -Supported Pt with Applications in Fuel-Cells

Cotet L.C., Andronie A., Stamatin I., Stamatin I.D., Stamatin I., Stamatin I.D., Cosoveanu V., Danciu V., Babes-Bolyai University, RO

Carbon–supported Pt materials still remain as reference electrocatalysts for the reactions in fuel cells [1]. Related to cost–performances carbon aerogel-supported Pt joins the catalytic properties of the Pt with attractive structural properties of the aerogels, [...]

Structural Stability of Hydrogen Storage Materials

Katagiri M., Onodera H., Ogawa H., National Institute for Materials Science, JP

Elastic instability by hydrogenation and hydrogen diffusion are studied by molecular dynamics method. The bulk modulus instability causes the anorphization by hydrogenation. The atomic relaxation reduces the pressure fluctuation terms i n the elastic constant, [...]

Study on the Cathode Materials for Achieving IT-SOFC with Proton Conductor

Asamoto M., Miyake S., Yonei Y., Yamaura H., Yahiro H., Ehime University, JP

Proton conductor is the potential candidate as an electrolyte for an intermediate temperature-solid oxide fuel cell (IT-SOFC). However, a major issue with the reduced operating temperature is the decrease in the catalytic activity of the [...]

Zirconia Aerogel-Polyxometalate Composites Synthesis with Applications in Solid Oxide/Acid Fuell Cells

Nicoara A., Cosoveanu V., Ladiu I., Baia L., Baia M., Baia L., Baia M., Muresan L., Stamatin I., Danciu V., Babes-Bolyai University cluj-Napoca, RO

Zirconia is based material with various applications in catalysis, oxygen sensors, SOFC and electrochemical pumps. Zirconia aerogels dopped or functionalized with solid heteropolyacids extend applications to high performances materials with improved features such as: high [...]

Computer Simulation of Hydrogen Storage Materials

Katagiri M., Onodera H., Ogawa H., National Institute for Materials Science, JP

We develope a new software to design the hydrogen storage materials. The energetic and dynamical behavior of the materials are studied. As an example, we illustrate the amorphization process of intermetallics by hydrogenation, i.e. hydrogen [...]

New Catalytic system for Producing Pure Hydrogen -Water-gas-shift Reaction of Supported Copper Catalysts-

Yahiro H., Saiki K., Yamamoto T., Sagata K., Asamoto M., Yamaura H., Ehime University, JP

The catalytic activity of water-gas-shift (WGS) reaction was investigated for alumina-supported copper and copper-iron oxides catalysts calcined at different temperatures. Alumina-supported copper catalysts calcined at 1073 K, followed by the treatment in H2 at 523 [...]

Development of Efficient, Compact and Environmentally Friendly Hydrocarbon Reformer for the Production of Pure Hydrogen

Ciocci R., Abu-Mahfouz I., Elnashaie S., Penn State University at Harrisburg, US

Hydrogen represents one of the most promising clean fuels for the future. Reforming of hydrocarbons (e.g. natural gas, gasoline, diesel, etc.) represents the most promising route for the production of hydrogen because it yields hydrogen [...]

Bifurcation Behavior of a Novel Auto-thermal Circulating Fluidized Bed (CFB) Membrane Reformer

Abu-Mahfouz I., Elnashaie S., Ciocci R., Penn State University at Harrisburg, US

Static Bifurcation (SB), which mostly exhibits itself as multiple steady states, is characteristic of a novel auto-thermal Circulating Fluidized Bed Membrane Steam Reformer (CFB_MSR) for hydrocarbons. The present paper focuses on the practical implications of [...]

Nanomaterials for Desulfurization & Hydrogen Generation

Venugopal G., Vylkov N., Unfried K., Sapp M., Hunt A., nGimat Co., US

Energy R&D is being driven by concerns about global warming and air pollution largely attributed to pollutants from the burning of fossil fuels. While long-term energy strategies may call for the complete replacement of petroleum-based [...]
