Success in developing groundbreaking electrolyte materials

-One step forward for commercialization of SOFC-

22 Nov, 2010

Two types of novel proton conducting oxide electrolytes for solid oxide fuel cells (SOFCs) have been successfully developed. By applying these electrolytes, the commercialization of SOFCs operating in the intermediate temperature range, 500 to 650°C, has come into sight.
