The interplay between automation and energy technology, IT platforms and artificial intelligence is the focus of the HANNOVER MESSE 2018 being held from April 23-27, 2018. At the renowned international trade fair, the Fraunhofer Institute for Solar Energy Systems ISE presents innovations in hydrogen technology at the joint booth »Hydrogen + Fuel Cells + Batteries« (Hall 27, Booth C58). A highlight at the booth will be the presentation of the GreenTec Award 2018 in the category »Energy« on Tuesday, April 24th at 2 pm.
Functional Laboratory Test Cell for PEM Water Electrolysis
The test cell made of transparent plastic has been successfully implemented in research projects at Fraunhofer ISE for many years.

The functional cell is pressure-tight up to 50 bars and serves to analyze membrane electrode units for PEM electrolysis. The integrated reference electrode for the anode and cathode are a unique feature. In newer versions the press force can be selectively adjusted.
Municipal Vehicle with Fuel Cell Hybrid Drive
In the ELAAN project (https://www.ise.fraunhofer.de/en/research-projects/elaan.html), the project partners developed a municipal vehicle with a fuel cell hybrid drive. After analyzing of typical driving profiles and assessing the resulting power performance requirements, it was determined that two 10 kWel fuel cell systems from Fronius, based on a PEM fuel cell stack by Elring Klinger, would be used. The Fraunhofer ISE carried out an extensive sensitivity analysis of the fuel cell stack in order to define the optimal operating conditions for the fuel cell. At the same time, detailed models of the fuel cell system, the stack and essential system components were developed to optimize operating strategies.
Differential Test Cell for Fuel Cell Components
For the characterization of material and components of low-temperature PEM fuel cells (LT-PEMFC), differential test cells are preferred. Fraunhofer ISE and the company balticFuelCells GmbH developed such a test cell corresponding to the state-of-the-art in science and technology: a minimized temperature gradient of ca. 1 K (operation up to 5 A/cm²), extremely homogeneous and precise pressing of the active area and optimized handling for fast and reliable material and component screening.
Hydrogen Feed-in Plant to Support Sector Coupling
The model shows the hydrogen generation plant for feed-in to the natural gas distribution grid in the project »Freiburg Communal Energy Network.« The hydrogen generated by a PEM electrolyzer is fed into the local natural gas grid. A gas buffer storage decouples the electricity and gas grids. The plant control is carried out using complex model predictive control algorithms and live data from the European Energy Exchange (EEX) Day Ahead markets.

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.
DNA is not only a popular research topic because it contains the blueprint for life – it can also be used to produce tiny components for technical applications.
