Better fuel cell ion conductor reveals new science


TiTech fuelcell material density de-texted

The material is actually a ‘dual-ion conductor’, which allows both protons and oxide ions to defuse, and can “realise high total conductivity at lower temperatures and improve the performance of electro-chemical devices”, according to TItech.

Dual-ion conducting materials such as Ba7Nb4MoO20 are known but “their conductivities are not high enough for practical applications”, said the Institute, adding: “And their underlying conducting mechanisms are not well understood.”

The research team decided to riff on that particular known material, adjusting the molybdenum fraction with compositions following the formula Ba7Nb4-xMo1+xO20+x/2.
