Modern materials are often exposed to extraordinary loads. In order to achieve the best results in their field of application, they must combine a wide variety of characteristics.  For example, metals used in an aircraft engine must be highly stable and heat-resistant at the same time as being easy to shape. MAX-phase materials combine these and other qualities. In order to be able to use MAX phases industrially, scientists of the team around JARA-ENERGY member Prof. Olivier Guillon have developed a new manufacturing process.

Scientists from Forschungszentrum Jülich and the University of Münster have presented a new solid-state battery featuring an anode made of pure lithium. Lithium is considered an ideal electrode material which can help achieve extremely high energy densities. The metal is very reactive, which previously precluded its use as an anode material. This has now been made possible by means of two additional layers of a novel polymer. With Prof. Rüdiger A. Eichel and Prof. Florian Hausen, two JARA-ENERGY members are significantly involved in the investigations.

At the Institute for Combustion Technology at RWTH Aachen University, headed by JARA-ENERGY Member Prof. Heinz Pitsch, one major research objective deals with the challenges of hydrogen combustion in the context of sustainable energy concepts. Hydrogen represents a promising fuel, which combines a feasible and well understood production process with clean combustion. However, before hydrogen combustion becomes fully applicable in actual engines, a deeper understanding of its combustion behavior is required.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Scientists at the Institute of JARA-ENERGY member Prof. Rüdiger A. Eichel have now presented a new concept that allows ten times higher currents during charging and discharging than previously expected. The improvement was achieved by a "clever" choice of materials. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

Most of the automobiles on the roads today continue to move with conventional engines. Petrol and diesel are the predominant fuels. However, the environmental performance of these fuels is anything but green. For some years, not only the demand for alternatives has been increasing, but also the number offer of new technologies. Scientists from the Institute for Energy and Climate Research have now compared battery and fuel cell in a study and evaluated their profitability.

The Institute for General Mechanics (IAM) of the RWTH Aachen University and the Institute for Energy and Climate Research, Electrochemical Process Engineering (IEK-3) of the Research Center Jülich have been working together for a long time. The two institutes are managed by two JARA-ENERGY scientists, Prof. Bernd Markert (IAM) and Prof. Detlef Stolten (IEK-3).

The common goal is the research, development and optimization of porous materials as central components of electrochemical energy conversion equipment. A recent joint study aims to improve the design of Polymer Electrolyte Fuel Cells (PEFC) by a deep understanding of the functionality and optimization of the design of the porous gas diffusion layer (GDL), the main gate of reactants from the gas channels to the catalyst layer of the PEFC.

In combustion processes of hydrocarbon-containing fuels, pollutants, such as unburned hydrocarbons (UHC), carbon monoxide (CO), oxides of nitrogen, collectively referred to as NOx, and particulates in the form of soot, are formed and emitted into the atmosphere. The severe environmental effects of increased ambient NOx concentrations have led to stringent emission laws and as a result. A promising tool to accomplish this goal is the design and control of these systems using computational fluid dynamics (CFD).
