001046967 520__ $$aSolid state proton conducting fuel and electrolysis cells 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.
