2. Suppose a new fuel cell is proposed, working on the gas-phase reaction CO + 02 → CO₂ 1 (such devices already exist in the solid state this question will assume just gas phase reactions etc). If the device is to operate at a temperature of 400K and initially at a pressure of 1 bar: (a) Calculate the open circuit voltage produced by the fuel cell (b) Calculate the mass flow rate (in kg/hr) of CO required to produce a power output 1kW (c) Calculate the entropy change of the system during the reaction (d) Calculate the heat rejected to maintain isothermal conditions (e) Calculate the irreversibility arising as a result of the fuel cell's operation. (f) As part of the design revision, the operating pressure is raised to 35bar, with the temperature maintained constant. Repeat steps 1-5; what observations do you make?
