Fig. 7: Electrolysis performance, Faraday efficiency, and tolerance of single cells in EC mode.

a I–V curves of a single cell with C/H-BSCF air electrode in EC mode at 500–650 °C. b Comparison of current density of C/H-BSCF electrode and state-of-the-art electrodes at different temperatures. c The Rp was measured for single cells with C-BSCF, C/H-BSCF, and H-BSCF electrodes at 1.3 V in EC mode. d FE of the single cell with C/H-BSCF electrodes measured at 600 °C and –1 A cm-2 for different water pressures (20%, 30% and 40% H2O-air). e Hydrogen production rate and FE of cells at different current densities. f The tolerance of cell with C/H-BSCF electrode at different current densities and g long-term stability tests in EC mode. h The R-PCEC with C/H-BSCF air electrode performed cyclic tests in FC and EC modes.
