Materials and Components processing for advanced Energy Conversion Systems


Abstract:

Energy conversion for electricity generation is steadily improved by use of new or modified materials in combination with adjusted methods of processing.

The common goals thereby consist of efficiency enhancement, reduction of emission as well as cost reduction.

Concerning future fossil power plants new high-temperature, high pressure materials are developed e.g. new ceramic thermal barrier coatings are constructed by use of plasma spraying from (nano) suspension precursors allowing enhanced hot gas temperatures.
Looking to the upcoming carbon capture and storage uncertainty an alternative on membrane gas separation technology is being developed by constructing a graded material assembly from coarse grained substrate to nanosized top layers taking over the gas separation task, where wet chemical synthesis and deposition methods like Sol-Gel are used.

New direct conversion systems like fuel cells are intensively developed since a couple of years having the potential of high efficiencies even in small unit sizes. The solid oxide fuel cell which is a multifunctional layer device is being processed by using newly developed functional materials and a spectrum of high tech coating methods to obtain the desired dimensions with optimized microstructures and interfaces for enhanced catalytic and charge (ion) transfer.
