Analysis of Water Production of a 1.2 KW PEM Fuel Cell

Investigation of water production rate is one of the most important factors to evaluate the performance of a PEM Fuel Cell. In the present case water production rate was studied from the hydrogen and the air inputs with an additional consideration of the effect of the relative humidity of ambient air. A corrected model was used to evaluate the water production, and it was compared against experimental data. It was found that this new model is strongly enhanced and it becomes in a new focus of study. The fuel cell system was tested at steady state conditions during 2700 s at 245 W and 36 V. The mass flow rate of water produced by the experimental result was 1.444 grams/min, while the analytical result was 1.311grams/min; the error of the analytical data compared with the experimental data was 10.14 percent.
