Considera hydrogen-concentrationfuel cell is examined a concentration cell, that consists of pressurized hydrogen fuel compartment and an evacuated ultra-low-pressure vacuum compartment separated by a composite platinum-electrolyte-platinummembra ne structure. This cell contains no oxygen to react with the hydrogen, yet it will produce energy. If the hydrogen compartment is pressurized to 150 atm H2and the vacuum compartment is evacuated to 10-7atm, what voltage will this unit produced as determined by the Nernst equation
