Abstract�� Polymer electrolyte membrane (PEM) is used as the electrolyte in polymer electrolyte membrane fuel cell (PEMFC).Presently,a large amount of work has been devoted to improve the performance of PEMFC to achieve their widespread applications,including the topic about humidifying technology for PEM in order to maintain the proton conductivity.In this article the humidifying methods that have been applied or in the process of study are reviewed.The method of self-humidifying has been paid more attention because it can predigest the external assistant equipments and reduce the weight and the volume of the cells.��
