The isothermal operation of single PEM fuel cells below 0 °C is investigated by potentiostatic experiments and analyzed by physical modeling. Current decay is observed during potentiostatic operation, which is caused by the freezing of product water

A one-dimensional model of the PEM fuel cell cathode is developed to analyse AC impedance spectra and polarisation curves. The porous gas diffusion electrode is assumed to consist of a network of dispersed catalyst (Pt/C) forming spherically shaped a
