Abstract:	The development of a generalized steady-state electrochemical model of a polymer electrolyte fuel cell or proton exchange membrane fuel cell (PEMFC) system is presented by R.F Mann et al. to predict the output voltage of a single Ballard Mark V cell as a function of the major variables like current density, pressure of the reactant gases and working temperature more efficiently (Mann et al. 2000). But this model cannot explain the behavior of the voltage at high current densities as well as the other ranges. In this research a new term that account for mass transfer losses is added to compensate the precision of the model particularity at high current densities. Using this model, the power density of a Ballard Mark V fuel cell system that consists of 35 cells is optimized by a hybrid optimization algorithm base on genetic algorithm and a gradient base algorithm that shows very good performance to reach the exact optimum point.
