A fuel cell vehicle with a similar volume fuel tank can store 400 g of hydrogen at

Question:

A fuel cell vehicle with a similar volume fuel tank can store 400 g of hydrogen at high pressure.

■ 2 g of hydrogen release 286 000 J of energy when used in the vehicle’s fuel cells.

■ 60% of the energy released from the fuel cell is converted into useful work.

■ 1 × 10⁶ J of work is needed to drive the car 1 km.

a. How many joules of energy are released when 400 g of hydrogen is used in the vehicle’s fuel cells?

b. How many of these joules of energy are available to move the car forward?

c. How far can the car travel on 400 g of hydrogen?
