Proton conductor NASICON-structure Li1+xCdx/2Zr2−x/2(PO4)3 as solid electrolyte for intermediate-temperature fuel cells

Lithium doping creates abundant interstitial ion migration space; the proton's lower migration barrier enables NASICON Li 1+ x Cd x /2 Zr 2− x /2 (PO 4 ) 3 , a promising proton conductor.
