Project Information

The COMPASS project is a collaborative effort of AVL, Plansee, Nissan and Research Center Jülich to develop advanced SOFC APU systems for range extender applications in passenger cars. The consortium is perfectly integrated from powder-, cell-, stack-, APU system technology providers to vehicle manufacturer and an academic partner. The project will use innovative metal supported SOFC stack technology, which enables key features like rapid start up and mechanical robustness for this application. Within the project, advanced APU systems will be developed with electrical efficiency above 50%, a start-up time below 15min and a small packaging size suitable for integration into battery electrical vehicles.

The general objectives of the project are:
  • Development of an advanced & highly efficient SOFC APU system for range extender purposes of battery electric passenger vehicle
  • Integration of the APU system into a prototype/concept vehicle (electrical, mechanical, thermal, functional and safety)
  • Development of advanced operating strategies and hybridization approaches to maximise the overall powertrain efficiency
  • Systemic analyses of degradation mechanism and development of validation test protocols for innovative SOFC MSC (metal-supported-cell) technology
  • Durability and reliability tests on stack and APU system 

Technical Approach

Under the lead of NISSAN also a prototype vehicle will be build up, where an APU system will be completely integrated into the electrical powertrain.

A major focus of the project is technology validation and systematic durability/reliability development. Therefore, in a specific work package all validation activities are concentrated. The validation testing includes tests on stack, APU system and vehicle level.
This project is an innovative approach to integrate SOFC APU systems into electrical powertrains and will help to significantly improve APU systems also for other applications like heavy duty trucks, marine and leisure/camping.

Project Structure

The COMPASS consortium is composed of four partners from three European countries. A strength of the COMPASS consortium is integration from industry and academic partners. This unique combination within this small ecosystem strongly supports know-how transfer and identification of cross-domain, innovative solutions.

The project is divided in six work packages. While project management and cost analysis run throughout the project, the other four work packages are consecutively structures.
