The water distribution within a polymer electrolyte fuel cell (PEFC) has been modeled at various levels of sophisti- cation by several groups. The focus of this research is the development and use of a sub-freezing thermal model for a polymer electrolyte fuel cell stack. These advantages of the PEFC make it particularly suitable for automotive application. Polymer electrolyte membrane fuel cells (PEMFC) are a promising technology for economic and environmentally friendly energy production. of fuel cells, the polymer electrolyte fuel cell (PEFC) has received the most attention and been investigated more thoroughly because it can operate at high power densities and low temperatures compared to other types of fuel cells [1]. Polymer electrolyte membrane (PEM) fuel cells, which convert the chemical energy stored in hydrogen fuel directly and efficiently to electrical energy with water as the only byproduct, have the potential to reduce our energy use, pollutant emissions, and dependence on fossil fuels.
It also serves as the basis for many different commercial PEFC … Z. T. Xia and S. H. Chan, “Analysis of carbon-filled gas diffusion layer for H 2 /air polymer electrolyte fuel cells with an improved empirical voltage-current model,” International Journal of Hydrogen Energy, vol. The possibility of hydrogen production from renewable energy sources increases the availability of hydrogen that causes more attention to Fuel Cells. First, various time constants are estimated for important transient phenomena of electrochemical double-layer discharging, gas transport through the gas diffusion layer (GDL) and membrane hydration. Polymer electrolyte membrane Fuel Cell (PEMFC) has been one of the most important clean energy sources in recent years. A polymer electrolyte membrane that conducts protons A parametric model predicting the performance of a solid polymer electrolyte, proton exchange membrane (PEM) fuel cell has been developed using a combination of mechanistic and empirical modeling techniques. 7, pp. 0378-7753, 163, pp. However, the most common fuel cell classification is by type of electrolyte: polymer electrolyte membrane fuel cell (PEMFC), alkaline fuel cell (AFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC), and solid oxide fuel cell (SOFC) [2].

Verbrugge and Hill (2-4) have carried out extensive modeling of transport properties in perfluorosulfonate ionomers based on dilute solution theory. A parametric model predicting the performance of a solid polymer electrolyte, proton exchange membrane (PEM) fuel cell has been developed using a combination of mechanistic and empirical modeling techniques. This paper details the mechanistic model development.
Basic Principle of Fuel Cell Modeling Polymer electrolyte fuel cells are electrochemical devices, converting the chemical energy of fuel directly into electrical energy. A three-dimensional, transient model has been developed to study the transient dynamics of polymer electrolyte fuel cell (PEFC) operation.
