| Summary, etc. |
Proton exchange membrane electrolysis cell (PEMEC)is one of the most promising methods to produce hydrogen at high purity and low power consumption. In this study, a three-dimensional non-isothermal model is used to simulate the cell performance of a typical PEMEC based on computational fluid dynamics (CFD)with the finite element method. Then, the model is used to investigate the distributions of current density, species concentration, and temperature at the membrane/catalyst (MEM/CL)interface. Also, the effects of operating conditions and design parameters on the polarization curve, specific electrical energy demand, and electrical cell efficiency are studied. The results show that the maximum distribution of current density, hydrogen concentration, oxygen concentration, and temperature occur beneath the core ribs and increase towards the channel outlet, while the maximum water concentration distribution happens under the channel and decreases towards the channel exit direction. The increase in gas diffusion layer (GDL)thickness reduces the uneven distribution of the contour at the MEM/CL interface. It is also found that increasing the operating temperature from 323 K to 363 K reduces the cell voltage and specific energy demand. The hydrogen ion diffusion degrades with increasing the cathode pressure, which increases the specific energy demand and reduces the electrical cell efficiency. Furthermore, increasing the thickness of the GDL and membrane rises the specific energy demand and lowers the electrical efficiency, but increasing GDL porosity reduces the specific electrical energy demand and improves the electrical cell efficiency; thus using a thin membrane and GDL is recommended. |
