Consider a fuel cell vehicle. The vehicle draws 30 kW of power at 60 km/hr and is 50% efficient at rated power. (It converts 50% of the energy stored in the hydrogen fuel to electric power.) You are asked to size the fuel cell system so that a driver can go at least 300 km at 60 km/hr before refueling. Specify the minimum volume and mass requirements for the fuel cell system (fuel cell + fuel tank) given the following information:a. Fuel cell power density: 1 kW/L, 500 W/kg b. Fuel tank energy density (compressed hydrogen): 4 MJ/L, 70 MJ/k 10. Consider a fuel cell vehicle. The vehicle draws 30 kW of power at 60 km/hr and is 50%efficient at rated power.

Question

Consider a fuel cell vehicle. The vehicle draws 30 kW of power at 60 km/hr and is 50%
efficient at rated power. (It converts 50% of the energy stored in the hydrogen fuel to
electric power.) You are asked to size the fuel cell system so that a driver can go at least
300 km at 60 km/hr before refueling. Specify the minimum volume and mass requirements
for the fuel cell system (fuel cell + fuel tank) given the following information:
a. Fuel cell power density: 1 kW/L, 500 W/kg
b. Fuel tank energy density (compressed hydrogen): 4 MJ/L, 70 MJ/k
