【 摘 要 】

The present study focusses on the results of a numerical work carried out on a proton exchange membrane fuel cell with an active area of the bipolar plate as 50 cm2. The investigations are employed on various operating conditions such as different flow rates of hydrogen and oxygen, cell voltage and temperature. Assumptions made in the study are steady state, single phase, laminar, compressible ideal gasses, the by-product water in liquid phase, transfer of heat in the cell only through conduction mode and so on. The landing to channel ratio employed in the present study is 1:1. The results obtained from the numerical investigations are validated with the help of an experimental study on a 50 cm2 serpentine channel of a bipolar plate in a proton exchange membrane fuel cell with same operating parameters. Results show that mass flow rates and temperature have a significant effect on the performance of the fuel cell.
