The efficiency of a fuel cell is an indicator of the efficiency
of the energy conversion, whereby a differentiation is made between
two efficiency types, the energetic efficiency and the faradic
The recovery of electric energy from the energy stored in the
hydrogen and oxygen must take place as efficiently as possible, as
this is important for cost effectiveness.
The efficiency is dependent on many different factors. A few
examples of them are how moist the fuel cell is, at which
temperature it is operated and which value the atmospheric pressure
has. It is therefore not unusual for the efficiency to differ with
different fuel cells.
In this experiment, the different efficiencies of a PEM fuel
cell are examined and calculated.
