Performance and Parameter Sensitivity Analysis of the PEMFC Flow Channel with Porous Baffles

Applied Sciences, 2021
In this paper, a method to improve the performance of PEMFCs using porous material as a flow channel baffle is proposed. The results show that PEMFCs with four porous baffles flow channels have better performance at high current density compared with the
