   Sammanfattning : The proton exchange membrane fuel cell generates electricity from hydrogen and oxygen (from air) through electrocatalytic reactions in an electrochemical cell. The Pt/C catalyst, commonly used in PEM fuel cells, is very sensitive to impurities that can interact with the active catalyst sites and limit fuel cell performance. LÄS MER

   Sammanfattning : Electroactive polymers (EAPs) are materials that can change their dimensions or shape in response to electric stimulation. They have attracted considerable interests for their applications as soft, lightweight and silently operating polymer actuators. One significant group of EAPs is conducting polymers. LÄS MER
