System expertise for fuel cell powertrains

Legislation governing vehicle emissions is becoming stricter, the climate debate and therefore also the development of alternative drives is gaining momentum. One promising solution is the fuel cell used to supply energy to an electric drive. MANN+HUMMEL has now developed an innovative air induction system for the cathode path in order to ensure an efficient supply of clean air to the fuel cell.
