Consider a fuel cell vehicle. The vehicle draws 30 kW of power at 60 mph and is 40% efficient at rated power. (It converts 40% of the energy stores in the hydrogen fuel to MAE 14:650:477 Alternative Energy Systems II electric power.) You are asked to size the fuel cell system so that a driver can go at least 300 miles at 60 mph before refueling. Specify the minimum volume and weight requirements for the fuel cell system (fuel cell + fuel tank) given the following information: • Fuel cell power density = 1 kW/L, 500 W/kg • Fuel take energy density (compressed hydrogen) = 4 MJ/L, 8 MJ/kg
