The fuel cell system delivers the performance

    • Air Intake

      The intake opening filters the dust particles out of the air, which delivers oxygen for the fuel cell stack.

    • Fuel Cell Control Unit

      The fuel cell system control unit reads the sensor value and thereby controls the actuators of the fuel cell system to ensure an adequate supply of hydrogen, air and sufficient cooling.

    • Power Distribution Unit

      The power distribution unit measures the current and voltage of the fuel cell stack and contains the main connectors for the HV system.

    • Electrical Turbo Charger

      The electrical turbocharger generates the airflow and the pressure that is required for efficient operation of the fuel cell stack.

    • Hydrogen Pressure Control Valve

      The hydrogen pressure control valve is used to set the pressure and flow of the anode circuit.

    • Humidifiers

      The humidifier increases the level of humidity in the intake air with water from the damp fuel-cell exhaust air.

    • Fuel Cell Stack

      The fuel cell stack is supplied with hydrogen and air. It delivers the electrical power and water. The only exhaust gas generated is pure water vapor.

How a Fuel Cell System Works

How a Fuel Cell Works

The systems developed by NuCellSys are based on PEM (Proton Exchange Membrane) fuel cells, which are operated using hydrogen and oxygen from the air.

  1. Hydrogen is supplied from the anode side, atmospheric oxygen from the cathode side.
  2. The hydrogen molecule H2 is split into two protons and two electrons via a platinum catalyst.
  3. Electrons flow as electrical current through various electrical consumers, while the protons diffuse through the membrane.
  4. The potential difference between the anode and cathode generate electrical voltage. By stacking several cells, the voltage of several cells can be combined.
  5. The oxygen molecule O2 is split catalytically at the cathode into two oxygen ions through the acceptance of four electrons. Every oxygen ion connects with two protons to form a water molecule.
  6. The water is carried out of the fuel cell by the airflow

The Hydrogen Tank System Determines the Range

 

    • Tank Filler Neck

      Refueling is performed by a globally standardized tank filler neck in accordance with the SAE J2601 protocol standard.

    • Hydrogen Filling Line

      During refueling, hydrogen flows from the tank filler neck through the hydrogen filling line to the tank containers.

    • Hydrogen Tank Containers

      The newest generation (Type 4) of hydrogen tank containers stores hydrogen at 700 bar/10,000 psi. The stored hydrogen reserves allow a range of ~ 500 km.

    • Hydrogen Container Valve Unit

      The hydrogen container valve unit provides reliable opening and closing of the tank container.

    • Tank System Control Unit

      The tank system control unit analyzes the sensor signal, calculates the tank content on the basis of the result and actuates the tank valve.

    • Hydrogen Pressure Control Unit

      The pressure control unit contains the pressure control valve and the system shut-off valve. The pressure valve reduces the hydrogen pressure from 700 bar to 12 bar.

    • System Shut-Off Valve

      The system shut-off valve separates the tank system reliably from the fuel cell system.

Hydrogen Filling Stations Define the Action Radius

400 hydrogen filling stations are due to be built in Germany by 2023
The Roadmap for H2 MOBILITY includes plans to build the first 100 hydrogen filling stations by 2018/2019. The aim is to have 10 stations in each of Germany's major urban centers: Hamburg, Berlin, the Rhine-Ruhr area, Frankfurt, Stuttgart and Munich, in addition to hydrogen corridors along highways.

The second project phase is geared towards the number of registrations granted for fuel cell vehicles. 400 hydrogen filling stations should allow for blanket coverage in Germany by 2023, thereby laying the foundations for an electro-mobile future.
