  1. Welcome tothe HyFacts Short Course • Chapter A: • Overview of hydrogen and fuel cell applications • Compiled by Christian Machens, TÜV SÜD Akademie

  2. Stationary H2storage 3D-representation of the system Container NRJTM(Reference: Axane) Note 1: dimension of the Container NRJTM: L 5,9 m • W 2,35 m • H 2,39 m (up to 5 hydrogen bundles can be stored in the system). Note 2: the top face or one side face of the container is opened, to ensure the appropriate ventilation of the container. Figure 1: Example of off-grid power supply system

  3. Stationaryfuelcells The Comm PacTM system for outdoor use, developed by Axane Note 1: pressure of the gas feeding the fuel cell: 10 bars (reduced to 250 mbar upstream the fuel cell) Note 2: ventilation grilles (close to the fuel cells) and a ventilation opening (above the hydrogen storage) have been included in the system design for safety reasons. Figure 2: Example of off-grid power supply system

  4. Material Handling applications with fuelcells Early market: Material handling vehicles or municipal vehicles Advantage: Short refuelling time Constant operating speed (As batteries get „weaker“, working speed decreases) No exchange of batteries necessary Less space required for refuelling (3 minutes consecutively) Power requirement: 1.5 – 10 kWel In operation: 2,300 pcs. in North America (2011) Refuelling: Either by hydrogen dispenser or exchange of bottles Picture 3: Forklifts with fuel cell

  5. Municipalvehicle with Fuel Cell Technical Data Max. Speed: 50 km/h FC: PEM 48V, 2.5 kWel • Additional advantages of FC operated vehicles: • Emission free • Silent operation • Auxiliary power supply possible (for tools, pumps, …) Picture 4: VEM H2 Fuel Cell utility vehicle (HyChain Project) Picture 5: H2 Pressure cylinders in the vehicle
