This article discusses a study conducted by researchers at Duke University's Pratt School of Engineering in Durham, North Carolina, which involved the development of a membrane that allows fuel cells to operate at low humidity and theoretically at higher temperatures. According to Mark Wiesner, professor of civil engineering, if the polymer membrane dries out, its efficiency drops. A ceramic membrane was developed using iron nanoparticles that works at much lower humidities and should tolerate higher temperatures.
