In order to understand the pressure effect on water mass fraction in the cathode for the PEM (Proton Exchange Membrane) fuel cell, a model was set up by three conservation equations, and it was considered the Gravity in source item. The modeling domain consists of the membrane, two catalyst layers, two diffusion layers, and two channels. It is simulation of species mass fraction in this paper. The...

It is helpful to highlight the performance of PEM(Proton Exchange Membrane) fuel cell that understanding of mass fraction inside PEM fuel cell. It is simulation of species mass fraction in this paper. Model was set up by three conservation equations, and it was considered the Gravity in source item. The modeling domain consists of the membrane, two catalyst layers, two diffusion layers, and two channels...
PEM fuel cell is a kind of generator with the characteristics of high efficiency and no pollution. Dynamic performance of current density distribution is important one of its parameters. In this paper, current density distribution measurement gasket and fuel cell test system were used to measure current density distribution in PEM fuel cells. Effects of fuel cell temperature and humidification temperature...
PEM fuel cell is a clean and high-efficient generation, which can be applied widely. Oxygen concentration of cathode reactants plays an important role on its performance. Performance of PEM fuel cell was surveyed by experiments in this paper. Influence of oxygen concentration on performance of PEM fuel cell is studied. Experimental results show that with the increase of oxygen concentration, open...
