Fuel Cells have been proposed for use in cars and for power generation as part of a hydrogen economy. They offer the advantages of higher efficiency (not limited by heat cycle effcencies) and cleaner fuel with no significant pllutants. The net reaction is as follows: 2H2+O2-> where O2 comes from air (which, for this provlem can be assumed to be 21mole% O2 and 79mole% N2). Hydrogen (H2) flows into a fuel cell implemented in a prototype vehicle at a rate of 27 gmol/min. Air (consisting of oxygen and nitrogen) enters he fuel cell in a seperate stream. The amount of ocugen entering the fuel cell is 50% more than that needed to react stochiometrically with all the entering hydrogen. The concersion of hydrogen in the fuel cell is 85%. Assume that only a single stream exits the fuel cell. What is the flow rate of each of the species leaving the fuel cell? Not that the flow rates given to correspond a fuel cell rate at approximately 50kW using 2004 technology.
