- Abstract
Tapered flow field configurations (FFCs) improve oxygen transport, water removal, and proton exchange membrane fuel cell performance. A three-dimensional multi-phase fuel cell model is used to quantify how the tapered FFC affects the internal physicochemical process and cell performance. The tapered FFC is compared without and with PMT and TCR. The tapered FFC with PMT and TCR increases oxygen delivery, water removal, and cell performance. In tapered FFCs with PMT and TCR, a more excellent LI/O ratio initially enhances but later worsens oxygen transport, water removal, and cell efficiency. Low LI/O ratios reduce cell performance regardless of FFC taper. The best tapered FFC design with a LI/O of 1.2 has more homogeneous reactant and current density profiles than other tapered FFC designs, decreasing the current density and oxygen mass fraction variation coefficient and improving cell performance.
