Cathode contamination modeling

Contamination models in the literature tend to be either empirical models or competitive adsorption models. Empirical models for air side contaminants [Pg.43]


Contamination in a PEM fuel cell directly affects the kinetics, conductivity, and mass transport properties of the cell. In particular, the blocking of electrocatalysts by impurity adsorption can drastically reduce the effective surface area of the catalysts and, thus, slow down the kinetics and hinder cell performance. This chapter is devoted to cathode contamination modeling. [Pg.180]

We have developed a general cathode contamination model [20] for PEM fuel cells, which is presented in this section. [Pg.186]

Besides the kinetic models we discussed above, the other cathode contamination models available in the literature are the empirical model and the competitive adsorption model [4,57]. Empirical models have been successfully used to describe FEM fuel cell performance at different temperatures and pressures [55,56]. Equation (6.73) was proposed by Kim et al. [56] ... [Pg.202]
