The challenge in designing a fuel cell electric drive lies in the vehicle- and vehicle application-specific dimensioning of the drivetrain components. The essential parameters to be considered for an optimization are the fuel cell output, the dynamics of the fuel cell, the mass of hydrogen in the tank, the capacity and maximum charging power of the HV battery, the output of the drive machine in motor and generator mode and also the dynamic behavior of the converters.
Startup company water stuff & sun has developed a novel technology that is designed to provide a safe and easy way to store hydrogen. The solution’s key component is its microvalve system. A pressure regulator controls the release of hydrogen progressively from 1,000 bar down to just a few bar. H2-international spoke to Thomas Korn, CEO of water stuff & sun, about how it works and the challenges encountered.
An electric moped with a 150-kilometer (90-mile) range that refuels in under a minute? With a fuel cell and hydrogen tank acting as a range extender, it is feasibly possible. Confirmation of this can be found in a joint study entitled “Pocket Rocket H2” that has been undertaken by DHBW university and SOL Motors in Böblingen, Germany.
Dr. Werner Tillmetz has not only promoted the advancement of hydrogen and fuel cell technology for many years, he has also at various points played a decisive role in shaping it – be it as a board member of the PV and fuel cell research institute of the state of Baden-Württemberg (Zentrum für Solar-...
