This paper presents a study of the fuel cell system performance operating at low pressure. A polymer electrolyte fuel cell (PEMFC) is analyzed in according with the possibility of using in transport applications. So, it begins with the description of a parametric model of the fuel cell which has been developed using a combination between empirical and mathematics modeling techniques. This model enables to model fuel cells V–J curves in dependences with the stack temperature and the oxygen partial pressure. Also, it can be used to study the influence of the gases management (pressure) on the fuel cell stack performances. The study continues with the modeling and simulation of a blower as the active element for the compression air system. One has used a least squares method for non-linear curves-fitting of fuel cell and blower.
