Customized electromagnetic and electrodynamic components for fuel cell drives in hydrogen applications.
HOW IS MAGNETBAU SCHRAMME POSITIONED IN THE FIELD OF FUEL CELL DRIVES?
- Hydrogen as a drive for so-called fuel cell vehicles.
- In general, these are electric vehicles which are additionally equipped with a hydrogen fuel cell including a hydrogen tank. The hydrogen fuel cell generates the electrical power to drive the vehicle while it is in motion.
- Today, hydrogen drives are used in cars, trucks, buses and rail vehicles.
- The electromagnetic and electrodynamic components in hydrogen applications must be able to withstand high pressures (> 700 bar).
- Analog and digital proportional controllers are used.
- Stainless steel is used for hydrogen applications.
- Pressure-tight laser welded joints made of austenitic and ferritic stainless steels are used.
- To be able to cover these requirements, Schramme brings a very high vertical range of manufacture to the value chain (CNC, welding, injection molding, assembly, QA/QM).
HOW DOES A FUEL CELL WORK IN AN ELECTRIC VEHICLE?
Structure:
- In the nearby picture, the fuel cell with anode, cathode and cooling heat exchanger is shown in the center.
- Coming from the left, the system is supplied with air (02).
- Coming from the right, the system is supplied with hydrogen (H2) via a dosing unit and a gas jet pump.
- Shown at the top of the picture is the motor and energy storage unit, which are supplied with energy from the fuel cell.
Functionality:
- Hydrogen is supplied to the anode compartment in the fuel cell from a compressed gas storage tank via a pressure control and dosing unit - the hydrogen is then fed into the anode compartment via a gas jet pump.
- The injected hydrogen in the anode of the fuel cell is never completely consumed during the process.
- By so-called recirculation with the aid of the water separator, the unused hydrogen can be fed back to the gas jet pump and thus to the fuel cell.
- Air is supplied to the cathode compartment of the fuel cell as oxygen (02).
- The product water flowing out of the cathode compartment is collected in the common storage volume.
- The current or energy generated by this process is used to drive the consumer (motor).
- The excess energy from the process can then be fed to an energy storage device (accumulator, battery).
