Overviews: Protonic Fuel cells”

The intermediate-temperature (IT) range of 300 to 600 °C has been accepted as the most desirable operating regime for fuel cells. The temperature interval referred to provide sufficient thermal energy to allow the use of less expensive catalysts, and also avoid severe damage to constituent materials. In this respect protonic ceramics have attracted attention due to their high ionic conductivity at intermediate temperatures. Protons in suitable selected ceramics can be transported with activation energies as low as 0.5 eV or below, and can exist at temperatures much higher than the boiling point of water (100 °C). In the two hour lecture first similarities and differences will be highlighted with regard to Protonic, PEM and SOFC Fuel cells. Then varios aspects which constitute the problem area of protonic fuel cells will be dealt with

Focused Ion Beams for Nanofabrication and Materials Characterization

Focused Ion Beam (FIB) instruments became extremely versatile tools for nanotechnology, materials science, and related fields. They have found widespread applications for nanofabrication of electronic and optical devices, failure analysis, and materials characterization. Therefore, having a heightened awareness of the broad capabilities of these modern workhorses of materials science is crucial. This lecture will review the basics of ion-matter interactions, different ion sources, and their specific advantages. Then, we will go through a variety of applications focusing on both the nanofabrication and characterization aspects from imaging to FIB-based tomography and the lamella preparation for TEMs and X-ray microscopes. At the end of the course, you will be able to identify cases where FIBs can provide a competitive advantage and insight to your processes.

“Electrochemical Impedance Spectroscopy for Solid Oxide Electrolysis/Fuel Cells  Research”

In the light of climate changes caused by anthropogenic CO2 emissions, efficient energy conversion and especially storage of excess sustainable energy are of increasing importance. Solid oxide electrolysis and fuel cells (SOECs & SOFCs) are expected to play an important role in future energy storage and conversion scenarios due to their high thermodynamic efficiency and large fuel flexibility reaching from hydrogen to carbon based fuels. For an efficient operation of SOECs & SOFCs, optimized materials such as solid electrolytes with high ion conductivity and best-performing electrodes are needed. Besides the individual materials, it is also often the numerous interfaces in these devices, which play an important role.
Impedance spectroscopy is a tool, which allows separation of individual electrochemical elementary parameters such as grain and grain boundary conductivities in solid electrolytes, surface and interface resistances in mixed conducting electrodes, and also capacitive contributions such as interfacial or chemical capacitances. This presentation deals with the role of impedance spectroscopy for the basic characterisation of materials used in SOECs/SOFCs. Discussed examples reach from conductivity measurements on electrolyte materials over material characterisation using geometrically well-defined model systems, to real 3D porous cermet electrodes.

Alexander K. Opitz is the head of the research group Electrochemical Energy Conversion at TU Wien(Vienna, Austria). There he also received his PhD in 2011. He was a visiting scientist at MIT in 2017 and returned to a tenure track position at TU Wien, where he is now an Assistant Professor in the research division of Technical Electrochemistry. He is doing research in the fields of Solid State Ionics (electrode kinetics, current pathways, and electrochemically active zones of solid state electrochemical systems), heterogeneous catalysis (in-situ spectroscopic and analytic studies on the surface chemistry and catalytic activity of electrodes), and materials chemistry (synthesis and characterization of novel, alternative materials for solid oxide cells).

Catalysis – A brief Overview

A catalyst is a substance that accelerates the rate of a chemical reaction by proceeding the chemical reaction on a new pathway with the lower activation energy. On the other hand, catalysis is the occurrence, study, and use of catalysts and catalytic processes. The science and technology of catalysis is of great significance as it affects our daily life. It finds applications in many important sectors of the world economy; petroleum and energy production, chemicals and polymer production, food industry and pollution control, energy storage and conversion etc. In this regard, catalysis is an interdisciplinary field of science that concern researchers in many fields of science. In this lecture, firstly important concepts and terms in catalysis will be introduced. Next, the concept of homogeneous and heterogeneous catalysis will be discussed considering the activity, reusability and lifetime of the catalysts. After the brief introduction to the fundamentals of catalysis, the rational design of catalysts with optimum activity and selectivity for the specific reactions will be discussed. In the final part of the lecture, a considerably significant time will be spent on the introduction to the nanocatalysis and the selected catalytic applications of transition metal nanoparticles in energy storage and conversion will be discussed.
