The direction is uncontroversial. If the EU wants to emit around 80 per cent less CO2 by 2050, there is no way of avoiding an energy revolution using green electricity from water, wind and sun and green hydrogen obtained from this electricity. Both energy carriers have to be comprehensive, safe and affordable – for vehicles, industrial processes and household applications.
AVL CEO Helmut List: “As a leading global technology company developing test stands for fuel-cell systems, AVL together with HyCentA is making an essential contribution to the development of sustainable and environmentally friendly power trains.”
Manfred Klell, scientific director of HyCentA, emphasises: “We have a highly integrated research environment in which we can work on application-oriented is-sues of fuel-cell systems holistically and for different applications. This test stand will help us con-tribute to making fuel-cell systems fit for the nationwide use of hydrogen as an energy carrier.”
The target group for joint research projects are, on the one hand, automotive suppliers who are interested in integrating the parameters of a fuel-cell system available on the market into their vehicle types, and on the other hand, producers of fuel-cell systems who want to sound out the possible uses and application characteristics of their prod-ucts.
High-dynamic test environment with a fully equipped virtual environment
This test infrastructure allows highly dynamic operating modes. Solutions for the development of motors in racing, such as for Formula 1, for example, allow for new dimensions of dynamics for try-ing out fuel-cell systems. In this outstanding test infrastructure, the load change is only limited by the fuel-cell system itself, which currently stands at 0.5 seconds. This means that experiments involving fuel-cell systems can be carried out under real load conditions and in dynamic operation. Researchers can trial concepts of energy management in fuel cells virtually and combine so-called “hardware in the loop” models on the test stand with real-time data of battery, e-motor or power train.
Starting efficiently at low temperatures
Fuel-cell systems also need to be optimised with regard to cold starting, since this represents a big challenge for material and operating strategies in automotive applications. Using the new test infra-structure, researchers can pay special attention to thermal management and the safe and efficient operation of fuel-cell systems at low temperatures. Another core focus is optimised heat removal and the design of the cooling system. There is even a focus on the potential for the use of waste heat.
Targeted premature ageing – accelerated ageing testing
Another application area of the new test stand is ageing in the service of science. To find out how long fuel-cell systems work under normal operating conditions, they have to age in fast motion. This is achieved by means of targeted loads outside the specifications but inside the design limits. Using special measuring technology, the main influencers on the duration of fuel-call systems can be exper-imentally identified and conclusions drawn.
Test stand is a Research Studio Austria
The costs of the whole research project amount to 2.3 million euros. Most of this comprises funds from the Research Studios AUSTRIA programme of the Austrian Research Promotion Agency (FFG) and the Federal Ministry of Science, Research and Economy (bmwfw). The Research Studios Austria (RSA) programme supports the application and implementation of research results from basic re-search in the forefront of corporate research in Austria.
This research area ist attributed to the Field of Expertise "Mobility & Production“, one of TU Graz' five strategic areas of research.
