Investigation of PEM Fuel Cell for Performance Augmentation: ANumerical Modeling Based Study

June 5, 2021 Engineering 0

Fuel cells are a promising clean renewable energy source that is now undergoing intensive scientific investigation and development. The Proton Exchange Membrane Fuel Cell (PEM), which is addressed in this study, is one of the most essential types of fuel cells. The purpose of this study was to develop a mathematical computerised model that could replicate the stages of a PEM fuel cell and look into the impact of cell design and operation parameters on overall performance. PEM fuel cells work at low temperatures and produce green corrosion inhibitors as a byproduct. enabling for quicker start-ups and rapid responsiveness to changes in power demand Membrane thickness, cell area, hydrogen pressure, and ionic current density are among them. The impacts of PEM fuel cell parameters on overall performance have been investigated using a onedimensional model. Even minute amounts of gas can infiltrate the membrane through minuscule pinholes, making fuel cells ineffective. Cell power (and electrical efficiency) declines as cell membrane thickness grows, according to the research. In addition, At a membrane thickness of 0.005 cm, the maximum value of cell power is attained, while the minimum value is reached at a membrane thickness of 0.05 cm. However, 0.81 A/cm2 is the ideal ionic current density for obtaining reasonably high cell power and electrical efficiency. These findings will aid in the development of novel PEM fuel cell designs and materials.
