Protonic ceramic electrochemical cells for hydrogen production and electricity generation: exceptional reversibility, stability, and demonstrated faradaic efficiency

We demonstrate exceptional performance for steam electrolysis at intermediate temperatures (500-650 °C) using protonic ceramic electrolyte cells comprised of the proton-permeable, high-activity mixed conductor PrBa 0.5 Sr 0.5 Co 1.5 Fe 0.5 O 5+ δ (PBSCF) as the air electrode, the highly proton-condu...
