Modeling and Analysis Approaches for PEMFCs
Författare
Summary, in English
Proton exchange membrane fuel cells (PEMFCs) are
expected to play a significant role in the next generation of
energy systems and road vehicles for transportation. To
achieve high performance, low cost and high reliability,
significant attention is needed on detailed modeling and
simulation of various physical processes in PEMFC unit-cells.
Substantial effort is also required to reach proper water and
thermal balances for PEMFC stacks and integrated energy
systems. For modeling and analysis at the unit-cell and
component level, typically CFD-based approaches might be
appropriate. On the stack and system levels, methods like
lumped parameter analysis and overall energy/mass balances
are more suitable. This paper discusses various kinds of
methods for modeling and analysis, and how these can be used
as well as their applicability and limitations. The focus is
placed on water management/two-phase flow regimes and
characteristics of relevant models.
