Abstract

This paper will present a reduced input non linear state space model which describes the dynamic performance of a Proton Exchange Membrane air‐hydrogen fuel cell (PEMFC). The mathematical model is based mainly on gases physical behaviour, which leads to reactants partial pressure evolution within the channels. In order to obtain a more realistic model, liquid water formation within the fuel cell channels; and its influence on the fuel cell voltage is considered from a probabilistic approach. Model simulations under dynamic charge conditions are validated using results obtained from experiments done with a 500 W fuel cell existing in our laboratory (L2ES).

A method is presented for classification of trend curves based on the linear state space model. In this approach information about the smoothness of the trend curves is incorporated into the classification model by a nonstationary stochastic trend model and can thereby be used to obtain a better cla

## Abstract This paper describes a method for obtaining a time continuous reduced order model (ROM) from a system of time continuous linear differential equations. These equations are first put into a time discrete form using a finite difference approximation. The unit sample responses of the discr
