Numerical Analysis of Number of blocks on PEM Fuel-cell Efficiency

This research paper delves into the analysis and comparison of two distinct geometries that can be employed to accommodate blocks in the oxygen channel. A fuel cell is an apparatus that generates electricity through the chemical reaction between hydrogen and oxygen, and this form of energy has garnered significant interest from scientists due to its eco-friendliness. The research team discovered that blocks can be strategically placed in the path of oxygen flow within a fuel cell to enhance its performance. By directing the oxygen fluid towards the membrane and gas diffusion layers, the contact surface between the hydrogen and oxygen fluids is augmented. The computational fluid dynamics technique was utilized to evaluate the efficacy of these channels. This approach relies on predicting fluid behavior by solving equations governing them using a computer. The study outlines the modeling and analysis stages of these channels. The team designed blocks in two different quantities, namely three blocks and ten blocks, with each block being triangular in shape.
