The PEFC generator for automotive application is expected to have a low cost,a low weight and a low size,to compete with more and more efficient combustion engine.To reach this aim,the complete system has to be taken into account,not only the stack itself,but also the fluid circuit ancillaries.A model is developed with the aim in view to be integrated in the simulation of an electrical vehicle power train.As many components have to be modelled,a macroscopic approach has been chosen.
