@article { , title = {Component-based modelling of PEM fuel cells with bond graphs}, abstract = {A polymer electrolyte membrane (PEM) fuel cell is a power generation device that transforms chemical energy contained within hydrogen and oxygen gases into useful electricity. The performance of a PEMFC unit is governed by three interdependent physical phenomena: heat, mass, and charge transfer. When modelling such a multi-physical system it is advantageous to use an approach capable of representing all the processes in a unified fashion. This paper presents a component-based model of PEMFCs developed using the bond graph (BG) technique in Modelica language. The basics of the BG method are outlined and a number of relevant publications are reviewed. Model assumptions and necessary equations for each fuel cell component are outlined. The overall model is constructed from a set of bond-graphic blocks within thermal, pneumatic and electrical domains. The model output was compared with the experimental data gathered from a two-cell stack and demonstrated a good accuracy in predicting system behaviour. In the future the designed model will be used for fuel cell reliability studies.}, doi = {10.1016/j.ijhydene.2017.09.004}, eissn = {0360-3199}, issn = {0360-3199}, issue = {49}, journal = {International Journal of Hydrogen Energy}, pages = {29406-29421}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://nottingham-repository.worktribe.com/output/899233}, volume = {42}, keyword = {PEM fuel cells, Bond graph, Multi-physics, Modeling, Modelica}, year = {2017}, author = {Vasilyev, A. and Andrews, John and Jackson, L.M. and Dunnett, S.J. and Davies, B.} }
