Abstract
An electrolyzer system includes an anticorrosive, conductive material including a first oxide having oxygen vacancies and a formula (Ia): MgTi2O5-δ (Ia), where δ is any number between 0 and 3 including a fractional part denoting the oxygen vacancies; and a second oxide having a formula (II): TiaOb (II), where 1<=a<=20 and 1<=b<=30, optionally including a fractional part, the first and second oxides of formulas (Ia) and (II) forming a polycrystalline matrix within the electrolyzer system.
