Andraž Kravos, Daniel Ritzberger, Christoph Hametner, Stefan Jakubek, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: PEM fuel cells;electrochemical PEM FC model;model-based design of experiments;reduced dimensionality models;parameter sensitivity;virtual observers;
Determination of the optimal design of experiments that enables efficient parametrisation of fuel cell (FC) model with a minimum parametrisation data-set is one of the key prerequisites for minimizing costs and effort of the parametrisation procedure. To efficiently tackle this challenge, the paper ...

Thermodynamically consistent reduced dimensionality electrochemical model for proton exchange membrane fuel cell performance modelling and control
Andraž Kravos, Daniel Ritzberger, Gregor Tavčar, Christoph Hametner, Stefan Jakubek, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: PEM fuel cells;electrochemical model;performance modelling;reduced dimensionality models;parameter sensitivity;observers;
The reduction and prevention of degradation effects of proton exchange membrane fuel cells calls for precise on-line monitoring and control tools such as coupled virtual observers. To present significant progress in the area of computationally fast electrochemical models used in observer application ...
