Parametric computational study of operating conditions on proton exchange membrane (PEM) fuel cells.
Chaudhary, Saket.

Parametric computational study of operating conditions on proton exchange membrane (PEM) fuel cells. - 106 p.

Source: Masters Abstracts International, Volume: 43-04, page: 1383.

Thesis (M.S.)--The University of Alabama in Huntsville, 2005.

The objective of this thesis work is to conduct a parametric numerical study on the effects of various operating conditions such as temperature, relative humidity, pressure, membrane thickness on proton-exchange-membrane (PEM) fuel cells. A computational model is used for both straight channel and serpentine fuel cells in two and three dimensions. The flow domain includes two main flow channels, a membrane, two catalyst layers and two diffusion layers. The results are compared with available experimental data where possible.

520 $a The objective of this thesis work is to conduct a parametric numerical study on the effects of various operating conditions such as temperature, relative humidity, pressure, membrane thickness on proton-exchange-membrane (PEM) fuel cells. A computational model is used for both straight channel and serpentine fuel cells in two and three dimensions. The flow domain includes two main flow channels, a membrane, two catalyst layers and two diffusion layers. The results are compared with available experimental data where possible.
520 $a The results show that the performance of the serpentine fuel cell increases with the increase of temperature, relative humidity and pressure. At higher temperatures the mass transfer within the fuel cell increases. A higher pressure at the cathode side forces the water back into the membrane, which increases the fuel cell performance. At higher relative humidity the membrane is sufficiently humidified leading to an increase in the fuel cell performance.
