This paper presents a new steady state model which contains fewer
polarisation curve fitting parameters compared to other semi-empirical
models. The established model is also defined at no load operation and can
be fitted perfectly to the static polarisation curve for a wide range of
cell currents. The model links the fuel cell voltage to the current by a
simple function to which various useful derivative laws can be applied. As a
result, many analytical expressions, for example, polarisation resistance or
power density, can be evaluated directly from the model.
