2. Hydrogen produced by steam-methane reforming exits at a pressure of 1.6 MPa and a temperature of 855°C. The hydrogen is stored in a metal hydride tank with a volume of 70 m³ and must be cooled down to a temperature of 30°C before being fed to a proton exchange membrane fuel cell. Determine the amount of heat transferred in cooling down the hydrogen obtained from the steam-methane reforming process. Assume hydrogen gas behaves ideally that the constant-volume heat capacity of hydrogen is given by the following equation: kJ mal °C C₂ ( 13 2.053x10-2 +7.650x10-6 T+3.288×10-9 T² -8.698x10-73
