Study the flow and species distribution characteristics in a typical 25-cell proton ceramic fuel cell stack by 3D large-scale modeling

Computational Fluid Dynamics for Protonic Ceramic Fuel Cell Stack Modeling: A Brief Review

“…Dai and their team also designed 3D models of PCFC stacks (25 cells) with two types of air-flow routes, such as U-type and Z-type, to investigate the best possible air-flow layout of the PCFC stack, as illustrated in Figure 6a [39]. This three-dimensional model of the air-flow path includes (a) one inlet manifold, (b) thirty-six rib channels to disperse the air-flow throughout the surface of the cell unit, and (c) a porous cathode current collector and function layers to improve the oxidant and product diffusions.…”

“…If both entry and exit of the inlet and outlet manifolds are situated on the same sides, it can be defined as a U-type path. In the Z-type air-flow pattern, the entrance of the inlet manifold and the exit of the outlet manifold are situated on opposite sides, as shown in Figure 6b [39]. They also constructed SOFC structures with U-and Z-type flow paths to compare and analyze the distribution characteristics with the PCFC stacks.…”

“…Based on that, mathematical modeling is a unique tool that has been created, which reduces the cost and dependency on repeated experimentation techniques. These needs are satisfied using CFD techniques to develop PCFCs [24,[38][39][40][41]. CFD tools help to study the transport processes and performance of PCFCs very quickly [35].…”

Three-dimensional multiphysics coupling numerical simulation of a proton conductor solid oxide fuel cell based on multi-defect transport

“…They found that the humidity of the inlet hydrogen had a significant effect on the current density, while the humidity of the inlet air had little effect. However, these models [25][26][27][28][29][30][31] are also 1D and 2D, and do not take into consideration heat transfer. A three-dimensional (3D) numerical model is needed when the gas partial pressure becomes important.…”
