Design a fuel cell stack for a fuel cell bus to operate at 200V and provides 100 HP, (1HP = 750 W). Assume the optimum current density on fuel cell electrode at 1 A/cm2. Thickness of each cell is 0.5cm, and nominal cell voltage is 1V. Calculate the power density of the fuel cell stack. Calculate the voltage drop of the fuel cell stack at 150A if the cell resistance is 2mW. Calculate the required hydrogen fuel (in kg) if the fuel cell operates continuously for 5-hours with 100HP.
