The standard heat of combustion for H2 to form liquid water is -285.84 kJ/mol. The standard equilibrium voltage for converting hydrogen and oxygen to liquid water is 1.229 V. a) Calculate the thermodynamic fuel efficiency for H2 in a fuel cell at 25°C. That is, what is the maximum fraction of the hydrogen’s energy content that can be converted to electrical work? b) If the fuel cell operates at 0.70 V, what fraction of the hydrogen’s energy content is converted to electric work?

Hydrogen reacts with oxygen to produce electrical energy in a fuel cell. 2H2(g) -> 4H+ + 4e- O2(g) + 4e- -> 2O2- 2H2(g) + O2(g) -> 2H2O(l)    Eo = +1.23 V Due to losses (typically heat) a fuel cell may actually produce about 1.0 V, but it is still more efficient than an internal combustion engine. The power in hydrogen can be expressed in units of Watts. The Watt in electricity is defined as the volts times current (amperes) 1...
