The reduction and prevention of degradation effects of proton exchange membrane (PEM) fuel cells calls for precise on-line control tools such as coupled virtual observes. To present significant progress in the area of computationally fast electrochemical models used in observer applications, this paper provides the derivation of easily invertible thermodynamically consistent electrochemical model of PEM fuel cell. Additionally, model exhibits very good extrapolation capabilities for operational points outside the calibrated variation space and enables successful parameterisation with little effort on small calibration data set. Thus, the model represents a key step in the further development of tools that will enable prolongation of remaining useful life of PEM fuel cells and, consequently, wider market adoption.

The results of the research are the fruit of a successful collaboration between the team of the Laboratory for Internal Combustion Engines and Electromobility – LICeM and the Institute of Mechanics and Mechatronics (TU Wien).  Recognition of the research actuality and relevance is confirmed by a recent publication in the prestigious journal - Journal of Power Sources with an impact factor 7.467.
