Ultrafast oxide-ion conductors pave way for low-temperature fuel cells

Researchers have developed ultrafast oxide-ion conductors that could enable solid-oxide fuel cells (SOFCs) to operate at lower temperatures. The advance supports fuel flexibility across hydrogen, natural gas and biogas with reduced energy losses.

• New oxide-ion conductors enable ultrafast ion transport
• Advance opens path to SOFCs operating at low temperatures
• Fuel cells can run on hydrogen, natural gas and biogas
