초록
A three dimensional numerical analysis was performed to study the PEMFC performance characteristics. Operating pressure and operating temperature were selected as simulation parameters. Operating pressure was varied as 1, 2, 3, 4, and 5 atm. Operating temperature was varied as 323, 333, 343, 353, and 363 K. For a constant cell voltage condition, the maximum current density was obtained at operating pressure of 5 atm and operating temperature of 323 K. As operating pressure increases, current density increases because concentration of reactant gases increases. As operating temperature increases, current density decreases because concentration of reactant gases decreases due to high overpotential condition for the considered PEMFC.
