Abstract
A mixed cation phosphate, NaMg 1− x Li x H x (PO 3 ) 3 · y H 2 O, exhibits a proton conductivity of over 10 −2 Scm −1 in the wide temperature range of 150–500 ° C under a non-humidified atmosphere, which is covering the desired operating temperature of fuel cells for automobiles and cogeneration systems.
