摘要: The steady-state heat transfer problem within a fuel cell is considered here. original 2-D defined while an averaging technique used in order to reduce its dimensions one. full equations along the appropriate boundary conditions are analytically solved for both solid and gas phase. Moreover, analytical expressions local as well overall coefficients obtained. temperature increases with distance current density, of always so low variation that can be constant. Finally, coefficient presents profile reverse temperature.
