The hydrogen-oxygen fuel cell is described in the text. For the questions below, assume the following: Assume that the air is 20 % O2 by volume and that all the O2 is consumed in the cell. The other components of air do not affect the fuel-cell reactions. Assume ideal gas behavior.

(a) What volume of H2(g), stored at 25.0°C at a pressure of 141 atm, would be needed to run an electric motor drawing a current of 8.50 A for 3.00 hr ?

b) What volume (in liters) of air at 25.0°C and 1.08 atm will have to pass into the cell per minute to run the motor ?

    Fuel cells can be powered by the reaction between formic acid and oxygen as following As formic acid and oxygen react together inside the fuel cell, it produced both electrical power and heat. While there is no shaft work produced by the fuel cells, this electrical power produced by the fuel cells can be considered as the shaft work term when you perform the energy balance. A fuel cell is being supplied with 100. liters per minute of pure formic...
