9 BATTERIES AND FUEL CELLS 235 9.5. A battery has specic capacity 252 C g density is 2.245 m g . 3 and mass of 50 g. Its overall (a) Find the specic capacity in mA·h g . (b) Find the capacity in mA·h. (c) Find the charge density in mA·h m 3 . 9.6. A battery has a specic capacity of 55 mA·h g and a nominal voltage of 2.4 V. The battery has a mass of 165 g. Find the energy stored in the battery inJ. 9.7. A battery has a sulfur cathode where the reactionS +2e − → S 2− occurs. The anode is made from a mystery material, X, and at the anode, the reaction X → X 2+ +2e − occurs. The theoretical specic capacity of the sulfur reactionis 1.76 A·h g and the theoretical specic capacity of material X is 0.819 A·h g . The theoretical specic capacity of the materials combined is 0.559 A·h g . What is material X, and what is V rp , the redox potential of the battery? (Hint: Use a periodic table and a list of redox potentials.) 9.8. What is the dierence betweeneach of the items inthe pairs below? • A battery and a fuel cell • A primary battery and a secondary battery • Redox potential and chemical potential 9.9. Consider the polymer electrolyte membrane fuel cell shown below. The reactions at the electrodes are: H 2 → 2H + +2e − 4e − +4H + + O 2 → 2H 2 O Match the label in the picture to the component name.
