So far, numerous modeling studies have been carried out to elucidate the electrochemical behavior of PEM fuel cells, and for this purpose, many empirical equations have been introduced to mimic the polarization curves. Srinivasan et al. [160, 161] developed the following equation to describe the relation between the cell voltage, E, and current density, i, in the low and intermediate current density ranges, where the electrochemical reaction is controlled by the activation and ohmic losses [Pg.73]

It is to such applications that the numerical model studies are directed. That is, the predictions of the model are [Pg.159]

To approximate this experimental observation and the results obtained from the three-dimensional numerical model study, the multiple shock Forest Fire model was used. The Forest Fire rate was determined by the first shock wave or the rates determined by any subsequent release waves that result in lower pressures and lower decomposition rates. As suggested by the three-dimensional study described in Chapter 3, the Arrhenius rate was added using the local partially burned explosive temperatures to the Forest Fire rate. [Pg.224]

In the following, the measurement techniques and the fundamentals of the numerical modelling studies as well as their application on small scale domestic wood stoves will be described. Furthermore, relevant experimental results and information obtained by the numerical modelling studies as well as a detailed comparison of measured and computed data will be shown by means of an example for a commercially available tile stove heating insert.
