Performance and transport characteristics of solid oxide fuel cells with counter flow arrangement
(2020) In International Journal of Electrochemical Science 15(2). p.1338-1346- Abstract
In this study, a two-dimensional model including the governing equations of mass, momentum, species, energy and charge, is developed and then applied to investigate the performance and multiphysics transport processes of solid oxide fuel cells with counter-flow arrangement. The current density and power density are calculated and presented, and the distributions of species and temperature are also analyzed. In addition, temperature distributions of fuel cells with varying operating temperature, anode inlet flow velocity and cathode inlet flow velocity are demonstrated. The results show that the temperature gradient increases with increasing operating temperature. And the local temperature decreases with increasing inlet flow velocities,... (More)

The results show that the temperature gradient increases with increasing operating temperature. And the local temperature decreases with increasing inlet flow velocities, especially the increasing cathode inlet flow velocity.
