Summary

The students describe and explain the thermodynamic and operating principles of internal combustion engines and all fuel cell types, identify the determining physical parameters for the operating regimes, the efficiencies and the polluting emissions, and compare the systems against each other.

• Design thermo-chemical and thermo-electric (fuel cells) conversion units, E18
• Explain and calculte the main emission sources of energy conversion processes, E23

Transversal skills

• Assess one's own level of skill acquisition, and plan their on-going learning goals.
• Communicate effectively with professionals from other disciplines.
• Access and evaluate appropriate sources of information.

Teaching methods

Ex cathedra with frequent questions. Resolved exercices.

Expected student activities

Solve the exercises by yourself.

Rehearse the previous course module for the following week

Assessment methods

Written exam, general knowledge questions and numerical resolution of exercices, on both course subjects (50% engines - 50% fuel cells).
