Dynamic response characteristics of a PEM Fuel cell were experimentally studied in this paper. The parameters subject to abrupt change include current, voltage and gas flow rate. It is found that with an abrupt change of current and voltage at low gas flow rate a steady state can be reached at much slower speed than high gas flow rate, while with an abrupt change of gas flow rate, the fuel cell can reach its steady state sooner at small current than at large current.
