The energy policy objectives of increasing energy efficiency, energy conservation, and the increased use of renewable energies call for rising efforts in the management of both electricity and heat and cannot be achieved without the development of improved conversion methods and utilisation techniques. The research area known as "energy process technology" with its conversion technologies such as fuel cells and electrical catalysts, storage technologies and new methods for fuel processing and hydrogen generation can render significant contributions.

Starting in 2007 the "energy process technology" area comprises fuel cell research (Electrochemical processes) and former activities of the combustion and gas turbine technologies (Thermochemical processes).

Electrochemical processes

As part of the DLR research field "electrochemical processes" developments of fuel cell technologies are being conducted that are focused on stationary power plants and aerospace applications .

Fuel cell applications in hybrid power plants (solid electrolyte fuel cell and gas turbine) and for domestic energy supply are of particular importance. Other projects deal with the application of fuel cells as auxiliary power units (APU) in vehicles where there is a significant synergy potential with the aviation and transport areas.

Common goals of the work performed in cooperation with industry and other research institutions, is cheaper and efficient manufacturing, to increase the durability of fuel cell components and stacks, and the optimal integration of stacks into systems.

Thermochemical processes

The research topic "thermochemical processes" deals with issues of energy storage - a subject important for all areas of energy supply and energy consumption. The increasing pressure to reduce fuel consumption requires the use of highly-efficient evaporators and condensers.

That is why high-performance heat exchangers are being developed that allow to realise high heat transfer coefficients. Furthermore, ceramic plate heat exchangers for the temperature range of 1000 to 1300 degrees Celsius are being developed that can be used in air or fumes. Process improvements for the production of hydrogen-rich fuels include studies upon the efficient delivery of syngas or hydrogen from fossil fuels and its storage. This includes the intelligent integration of the many thermal conversion steps into the overall process.
