        abstract = {The temperature of operation is a key parameter in determining the performance and
durability of a polymer electrolyte fuel cell (PEFC). Controlling temperature and understanding
its distribution and dynamic response is vital for effective operation and design
of better systems. The sensitivity to temperature means that uncertainty in this parameter
leads to variable response and can mask other factors affecting performance. It is
important to be able to determine the impact of temperature uncertainly and quantify
how much PEFC operation is influenced under different operating conditions.
Here, a simple lumped mathematical model is used to describe PEFC performance under
temperature uncertainty. An analytical approach gives a measure of the sensitivity
of performance to temperature at different nominal operating temperatures and electrical
loadings. Whereas a statistical approach, using Monte Carlo stochastic sampling,
provides a 'probability map' of PEFC polarisation behaviour. As such, a polarisation
'area' or 'band' is considered as opposed to a polarisation 'curve'. Results show that
temperature variation has the greatest effect at higher currents and lower nominal operating
temperatures. Thermal imaging of a commercial air-cooled stack is included to
illustrate the temporal and spatial temperature variation exerienced in real systems.},
