The present study mainly focuses on the different combinations of significant operating parameters like inlet relative humidity of anode gas and cathode gas, operating pressure and nature of cathode gas on the performance of Proton Exchange Membrane Fuel Cell (PEMFC) using validated three- dimensional (3D), single-phase, and non-isothermal model with the help of ANSYS Fluent 18.1 package. The results of different combinations on the performance of PEMFC are compared with independent effects of the operating parameters. Results revealed that the combined operating parameters? effect on the performance of the PEMFC is deviated significantly (up to 5 %) compared to the expected summation of individual parameters effect which is considerable in fuel cell scaling and stack applications. Nature of gas, operating pressure, and inlet cathode gas relative humidity are the most significant parameters in the automobile applications which have to be dealt with care where the combination of changes in operating parameters is quite phenomenal.

In this paper, the influence of the optimization for flow field size on the proton exchange membrane fuel cell (PEMFC) performance under the inadequate air supply of cathode was studied based on the three-dimensional, steady-state, and constant temperature PEMFC monomer model. Additionally, the effect of the optimization for hybrid factors, including length, width, depth and width-depth, on the PEMFC performance was also investigated. The results showed that the optimization of the flow field size can improve the performance of the PEMFC and ensure that it is close to the level under the normal gas supply.
