Fuel cells can be regarded as power generators. A conventional generator uses an internal combustion engine to rotate an alternator and generate electricity. On the other hand, a fuel cell generates power by harvesting the component electrons and protons of the fuel, converting them to electrical power.
In this context, the first unit recalls an introduction to auxiliary power unit and then presents the components of the balance of plant and the system layout.
The other part concerns electrical components description: high voltage connections, the power electronics and AC/DC converters. The various components are then assembled into a system for which a technician may encounter failures he must be able to understand and cope with dangers he must avoid when assuming maintenance or repair work.
Specifically the main aspects discussed in this course are:
Auxiliary power unit principle and market with emphasis on the existing APU devices and the latest developments
Basics of fuel cell based APU units with a description of fuel cell types, application and working principles
BoP components with detailed study of all the components (piping, fuel container, valves, air compressor, fuel reformer, heat exchangers .etc)
APU system layout with design and safety aspects
After finishing this course the student will be able:
- To identify fuel cell based generators, principles and typical fuels for APU units
- To identity BoP components and their design
To identify problematic parts in order to perform ordinary and extraordinary components maintenance
To detect any risk or incident related to the hydrogen technology
The qualification obtained is “Certificate of Knowledge in Hydrogen and Fuel Cell Technology for Technicians: Fuel cell based Generators”.
