Abstract
The various parameters affect the performance of the Proton Exchange Membrane Fuel Cell (PEMFC).
In this work, the performance of 81 cm2
active area with Rib to Channel width ratio of (R: C)-2:2 interdigitated flow
channel of PEMFC with various operating temperatures ranges (313, 3123, 333 and 343 K), pressure (1, 1.5, 2 and
2.5 bar) and various mass flow rate of hydrogen and oxygen (2.5, 3, 3.5 and 4) was analysed. The model was
developed and analysed using PRO-E software and the ANYSYS 14.0 software respectively. The L: C-2:2 has
produced the maximum power density was obtained as 0.199 W/cm2
at 2 bar pressure and 323 K on interdigitated flow
channel of PEMFC. Based on the optimization study by MINITAB 17 software, the square of response factor (R2
) was
achieved as 99.01%.
