Performance Change of PEMFC According to Flowfield

In this study, a performance comparison simulation according to the channel shape of a one-channel PEMFC was conducted using CFD. A simulation was conducted by changing the height and width of the channel. Furthermore, based on the I-V curve, it was confirmed that performance tends to increase as height decreases and width increases. Additionally, it was confirmed that the effect of the response area was greater than the effect of the channel area. Additionally, based on an additional performance comparison according to the porosity of the GDL and the relative humidity at the cathode, it was confirmed that the higher the porosity and relative humidity, the higher the performance.
