                      have attracted significant attention due to their potential
                      to operate at relatively low temperatures (400–600°C).
                      Electrolytes with reduced thickness can decrease ohmic
                      resistance, enabling enhanced cell performance under the
                      sluggish kinetics typical at low temperatures. Among the
                      ceramic thin-film deposition methods that are easy to
                      process and suitable for scale-up, such as tape casting and
                      screen printing, the capability of wet powder spraying for
                      preparing thin electrolytes has been largely underestimated.
                      Here, we developed a wet powder spraying process that
                      eliminates the need for additional organic additives such as
                      binders and dispersants in the suspension. The electrolytes
                      with thickness below 5 μm were we successfully fabricated
                      through parameter optimization.Besides, acceptor-doped
                      Ba(Zr, Ce)O₃ proton conductors has long suffered from
                      sintering challenges. Sintering at high temperature is
                      unavoidable due to the high refractory nature of its
                      constituent elements. However, Ba tends to evaporate at
                      elevated temperatures (above 1400°C), degrading
                      conductivity and cause B-site elements segregation. This
                      Ba-evaporation issue becomes particularly severe during
                      co-sintering of half-cells with thin electrolytes. We
                      propose two solutions: (1) optimizing substrate and
                      electrolyte compositions to lower the co-sintering
                      temperature; (2) employing a simple Ba compensation strategy
                      to counteract evaporation and improve sintering. Overall,
                      the combination of the wet powder spraying process and
                      sintering optimization enables the fabrication of thin,
                      dense electrolyte. The resulting full cells exhibit
                      promising electrochemical performance.},
