Functional Laboratory Test Cell for PEM Water Electrolysis

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.
