Welcome to the COMPASS project

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 supports SOFC stack technology, which enables key features like rapid start up and mechanic 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.

Project Objectives

This project aims to integrate SOFC based APUs (Auxiliary Power Units) into electrical powertrains. With this innovative approach, the attractiveness of Battery electric vehicles can be increased due to significant improvements in vehicle range and recharging times. Within the COMPASS project an advanced APU system will be developed, to convert chemical energy stored in a high energy density fuel tank (hydrocarbon, e.g. ethanol) into electricity, to recharge the vehicle HV battery for electrical driving. With this approach, the total range of the vehicle can be significantly increased, without adding more battery capacity. The project will focus on the development of an advanced APU system for range extension of battery electrical vehicles and on the other hand side on the validation of SOFC MSC stack technology and complete APU systems.
