Hydrogen flows into a fuel cell at a rate of 27 gmol/min. Air enters the fuel cell in a separate stream. The air stream flow rate ensures that oxygen is fed at 75% excess required for the stoichiometric reaction. All hydrogen is reacted. Assume that a single stream leaves the fuel cell. Calculate the mole fraction of oxygen in the outlet stream.
