Hydrogen (H) and oxygen (O.) are reacted in a fuel cell to produce energy. The product of the reaction is water, and any excess gases are vented after the fuel cell, as shown in the figure below. The hydrogen and oxygen tanks are maintained at the same temperature and pressure, and they feed at the same volumetric flow rate. The reaction goes to 60% completion in the fuel cell (hydrogen basis) If all of the unreacted hydrogen and a portion...
