| 英文摘要 | Application of a recently developed functionally graded porous material (FGPM) model to foam-based flow-distributor (FFD) in PEM fuel cells (FCs) is performed here. The volumetric power density (VPD) of the cell is compared with that of a conventional ribbed/channel parallel-serpentine one with 4-parallel channels (in short, 4-PS). Significant enhancement in VPD% is observed w.r.t. 4-PS case. Say, at current density 1 A cm(-2), the cell with FGPM-FFD provides 84% enhancement vs. 4-PS. The contributions to the enhancement come from two sources: (i) reductions in the cell volume and (ii) increases in generated electrical power. For the flow distributors studied here, the active area is fixed at 50 x 50 mm(2). While the 4-PS cell thickness is determined to be: 3.75 mm, from which 2 x 0.275 mm belongs to the gas diffusion layers (GDLs). In the absence of GDLs in the foam-based cells, the cell thicknesses reduce to 3.2 mm (~15% reduction in cell volume). Moreover, the generated electrical power is also higher in FGPM cells due to the rib-less nature of the foam-based flow distributors. For example, at 1 A cm(-2), the FGPM cell produces 57% more power than the 4-PS base case. At higher current densities, the enhancement is even higher. (C) 2022 Published by Elsevier Ltd. |
