4. Energy efficiency

The main advantage of a fuel cell for generating electrical energy, compared with an internal combustion engine coupled to an alternator, lies in its very high conversion efficiency.

  • The theoretical maximum efficiency of a thermal machine is given by Carnot's theorem:

    for T 1 = 723 K (450 °C) and T 2 = 353 K (80 °C) and
