A technique to be able to improve efficiency of PEFC (Polymer Electrolyte Fuel Cell) has been investigated by classification into over voltages. Effects of running condition on it were surveyed by using this technique. Results show that dry condition at MEA makes cathode activation and IR over voltage increase, and that wet condition increases cathode concentration over voltage caused by flooding. It is proved this technique could be able to obtain best running condition in trade off and to improve efficiency of PEFC.
