A fuel cell stack consists of 75 fuel cells arranged in series, each one 12cm^2 in size. The stack operates at 80.C and the amount of current generated is 4.257A/cm^2. The fuel cell operates at a system pressure of 1MPa using a supply of pure hydrogen and oxygen is ambient air. The partial pressure of the water in the outflow is 0.5 MPa. The reference voltage for a fuel cell at 80.C is E0=1.18 V. Assume any losses to be negligible and that the voltage at which it operates is the open circuit voltage; in reality, the voltage would be lower due to the current flow. What is the output of the fuel cell stack when operating at full capacity, in kW?
