A fuel cell vehicle draws 50 kW of power at 70 mph and is 40% efficient at rated power. You are asked to size the fuel cell system so that a driver can go at least 400 miles at 70 mph before refueling. Specify the minimum volume and weight requirements for the fuel cell system (fuel cell fuel tank): Fuel cell power density is 1.5 kW/L and 1 kW/kg (note: the values taken into account efficiency already). Fuel tank energy density (compressed hydrogen with the tank mass taken into account): 4 MJ/L and 8 MJ/kg.
