Scientists JARA have discovered a phenomenon similar to the laser effect with which the structure of organic molecules can be examined at previously unmatched levels of precision. In contrast to a laser, this "raser" (radiowave amplification by stimulated emission of radiation) is pumped with parahydrogen and does not operate at light frequencies, instead oscillating continuously at various radio frequencies of around 100 kHz. A precise fingerprint of the molecular structure can thus be obtained.

In order to create economic and technically feasible solutions for the conversion of energy system towards renewable energy sources, the Federal Ministry of Education and Research initiated the four Kopernikus projects. The partial project SynErgie investigates how energy-intense industrial processes can be flexibilized to adjust the industrial electricity consumption to a fluctuating electricity supply from renewable sources.

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.
