2. A proton exchange membrane fuel cell is fed a fuel gas of H2 from the anode side, while the cathode side is fed atmospheric air. Considering that the fuel cell is at room temperature, a) Calculate the cell potential (5 pts) b) Plot the changes in the cell potential as a function of temperature if the temperature is increased gradually to 80 °C at 5 °C steps (7 pts) c) Plot the changes in the cell potential as a function of fuel mixture composition if the hydrogen concentration is gradually reduced to 5% H2 and 95 % Argon (8 pts) 2.
