Hydrogen drive for BMW
Pierburg GmbH, which is part of the Rheinmetall Group, is participating in the development of a highly integrated high-power fuel cell drive system.
Hydrogen drive for BMW
The Neuss-based automotive supplier has developed a new type of hydrogen recirculation blower. Partners in this project of the German Federal Ministry of Transport and the National Organization for Hydrogen and Fuel Cell Technology are the automobile manufacturer BMW, the University of Siegen and other supplier companies. The task of Pierburg's new blower is to feed the hydrogen that was not used up during the reaction in the fuel cell back into the stack. The fan thus increases the efficiency of the fuel cell and extends its service life. In addition, the even distribution of hydrogen in the cell enables improved cold start behavior. The blower was developed in a low and high voltage version with up to 800 volts. “We are noticing increasing interest in fuel cells from almost all manufacturers on the market,” says Michael Becker, who heads advance development at Pierburg and coordinates fuel cell activities. “This applies on the one hand to larger cars and SUVs, but increasingly also to commercial vehicles, buses and stationary applications.”
