Course Overview
This training is an introduction of the Alstom Fuel Cell Composition (FCC) Technology.
- First, the participants receive information about hydrogen characteristics and the resulting hazards.
- Next the flow of energy from the hydrogen tank to the electric power leaving the FCC is clarified.
- The process path of hydrogen, oxygen and “exhaust” including all components needed is described.
- The components’ locations are shown on the FCC as well as in the wiring diagram. Purpose and function of all components are explained.
- The fuel cell power modules (FCPM) are explained more in detail (Input and output, components of the fuel cell stack, chemical reactions taking place within the fuel cells, necessary actions to ensure proper functionality and long lifetime of the material used within the fuel cells).
- The necessity, function, and components of the Thermal Management System (TMS) is explained. Striving for awareness of the importance of a proper working TMS and therefore the importance of reaching and keeping the optimal operating temperature.
- The FCC works with several voltage levels which are either provided by the train or by the power modules (FCPM). A deep understanding is essential to understand the total system function and to be able to do troubleshooting on the system.
- The importance of preventive maintenance is explained. The necessary tools are shown and used during the maintenance. The maintenance schedule is discussed, and the maintenance work (up to 12,000 operating hours) is done practically on the FCC.
- The application of the scan tool / E-Tool is demonstrated. The actual values, set values as well as faults and alarms set are explained and judged.
- Troubleshooting activities are explained by using:
- Wiring diagram
- Troubleshooting Trees (Fault Trees)
- Scan tool / E-Tool (e.g. FCCview)
- Wiring diagram
- The handling and usage of several measurement tools (e.g. Multimeter, LCR meter, conductivity meter) are shown and executed and the measurement values are judged accordingly.
- The necessity and importance as well as the process of purging the Hydrogen lines and the pressure test / leak test are declared.
- The test procedures valid for the Hydrogen recirculation pump (Inductance measurement, Hall sensor testing, HV Isolation Testing) are explained and shown.
- Correct removal and re-installation of FCC / FCPM components are shown and executed by the example of the Hydrogen recirculation pump and its controller.
Who should attend?
Especially new technicians in the field of New Power. It is a good way to step into the fuel cell technology.
