A comprehensive mathematical model of the performance of the cathode-supported solid oxide fuel cell (SOFC) with syngas fuel is presented. The model couples the intricate interdependency between the ionic conduction, electronic conduction, gas transport, the electrochemical reaction processes in the functional layers and on the electrode/electrolyte interfaces, methane steam reforming (MSR) and...

Abnormal growth of population and development enormously increases energy demand. In present scenario utilization of fossils fuels to meet this demand is not enough and also leads to pollution, global warming, climate change as well as natural disaster. Therefore, hydrogen as energy carrier is a major option on these prospects as it is non-polluting and renewable. The renewable hydrogen energy ...

Abstract Hydrogen production from renewable sources is gaining increasing importance for application as fuel, in particular with high efficiency and low impact devices such fuel cells. In addition, the possibility to produce more sustainable hydrogen industrial also of interest fundamental processes, ammonia methanol synthesis. Catalytic processes are used most options sources. Catalysts direct...

Ni nanoparticles supported on ZrO2 are a prototypical system for reforming catalysis converting methane to synthesis gas. Herein, we examine this catalyst on a fundamental level using a 2-fold approach employing industrial-grade catalysts as well as surface science based model catalysts. In both cases we examine the atomic (HRTEM/XRD/LEED) and electronic (XPS) structure, as well as the adsorpti...
