|Abstract: ||Reliability issues with fuel cells have held back the commercialisation of this
new technology, and as such are required to be studied further. Current
reliability standards for automotive applications require an operational life-
time of 150,000 miles or 5,000 hours. These standards are hard to achieve;
therefore in depth reliability analysis and degradation studies can help allude
towards the key areas of improvement in fuel cell technology to meet these
Previous Failure Mode and Effect Analysis (FMEA) work has shown
that the multi-component system of a Polymer Electrolyte Membrane Fuel
Cell (PEMFC) is inherently complex. Dependencies exist between multiple
failure modes which discounts Fault Tree Analysis (FTA) as a feasible reliability modelling technique. Therefore, in this study, Petri-Net simulation
and fuel cell modelling techniques have been adopted to develop an accurate
degradation model. Operational parameters such as water content, temperature and current density and their effects on the occurrence of failure modes
can be modelled through this technique. The work will improve previous
fuel cell reliability studies by taking into consideration; operating parameters (water content, temperature), fuel cell voltage based on demand (drive
cycles) and dependencies between failure modes.|
