1. On Gas Contaminants, and Bipolar Plates in Proton Exchange Membrane Fuel Cells
Abstract : The proton exchange membrane (PEM) fuel cell is an electrochemical device that converts chemical energy into electrical energy through two electrocatalytic reactions. The most common catalyst used is platinum on carbon (Pt/C), which has shown the best performance in the fuel cell until now. READ MORE

2. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia
Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE

3. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation
Abstract : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). READ MORE

4. Sintering of nickel catalysts in the presence of NH3/H2
Abstract : Supported metal catalysts are used in many important industrial processes, where amination of alcohols is one example. The exposure of the supported metal catalyst to reaction conditions results usually to a decrease in catalytic activity, by for instance thermal degradation. READ MORE

5. Studies of partial oxidation and combustion over heterogeneous catalysis by transient experiments
Abstract : Transient experiments are one of many techniques available to study heterogeneous catalysis and the catalysts used. The results obtained by transient experiments contain valuable information that is helpful in explaining reaction mechanism and interaction at the catalytic surface. READ MORE
