Pt- M (M = W, Mo, Sn)/C as anode catalyst for proton exchange fuel cell and system simulation of PEMFC

In this paper the Pt-M (M = W, Mo, Sn)/C as anode catalyst on single PEM fuel cell performance is investigated. For PtRu/C (commercial) gave a maximum power density of 139 mW/cm² at 357 mA/cm². The 20%Pt10%W/C shows the best performance and gives lower maximum power density 38% when compared to 20%Pt10%Ru/C (commercial), but the price of PtW is about 34% cheaper than the commercial PtRu/C catalyst. This result show that PtW are attractive alternative catalyst for PEMFC. A simplified static model of a fuel cell of proton exchange membrane (PEM) type, based on Pukrushpan´s model has been developed and describe in detail. The system simulation has been implemented in MATLAB/Simulink program. A quite good agreement has been found between test and simulation.
