Modelling Approaches to Mass Transfer and Compression Effects in PolymerElectrolyte Fuel Cells (Polymeerielektroly yttipolttokennojen Massansiirron ja Puristuspaineen Vaikutusten Mallintaminen)

摘要

The subject of this thesis is modelling polymer electrolyte membrane fuel cells (PEMFCs) locally and on a cell scale. The modelling was done using software based on the finite element method and focused on mass transfer issues and compression pressure distribution and its effects on local phenomena.
