abstract = {A dynamic model for the concentration admittance of a
polymer electrolyte fuel cell is presented. The model takes
into account oxygen transport in the cathode channel, the
gas diffusion layer, and the cathode catalyst layer. An
analytical solution for the concentration admittance is
derived. We observe that the admittance at the air channel
outlet is not affected by faradaic reactions, and it
contains information on the oxygen transport coefficients in
the cell. The admittance measured at the air channel outlet
can be fitted using the formula obtained in this work to
extract the oxygen transport coefficients. Practical methods
for measuring the concentration admittance are proposed.},
