.... Isothermal and adiabatic walls are chosen as the different boundary conditions in order to simulate the real situation, which lies somewhere in between. In the situation where adiabatic walls are assumed, the result shows that heat convection dominates the heat transfer process. However, heat conduction...

... heating the stack with external heating elements for start-up, heat conduction through stack insulation, cathode air convection, and heating of the inlet gases in the manifold. Various measurements are presented to validate the model predictions of the stack temperatures. With the measured temperatures...
