A SOFC is operated with an inlet flow of 20 g/s of pure hydrogen and an inlet flow
of 1450 g/s of air. If the fuel utilization is 50%, then determine the following
The mass flow rate out of the anode gas chamber
The mass flow rate out of the cathode gas chamber and the oxygen utilization
The current through the electric load
The power delivered to the load if the cell voltage was 0.8 volts
To determine the mass flow out of the anode we will need to know the flow
rate of H2 in, the rate of H2 consumption and the rate of H2O production.
Then application of a material balance around the anode will yield the flow
out of the anode. Although a mass balance is possible, we will go the route
of a mole balance. As such we begin by converting the anode inlet mass
flow rate into a molar flow
