This study demonstrates the effectiveness of using thin‐film electrolytes to enhance protonic ceramic fuel cells (PCFCs). The material tested in this study is yttrium‐doped barium cerate‐zirconate (BCZY), which is a representative electrolyte material of PCFCs. The thickness of the electrolyte membrane is as small as 1 µm and designed to minimize ohmic loss in proton transport pathways. Integration of this thin BCZY electrolyte is attempted on a multilayered anode comprised of two‐step supports with bulk nickel‐yttria stabilized zirconia cermet as a base and thin nickel‐BCZY as an anode functional layer atop the base. The compatibility of this support with the deposited thin electrolyte is able to be confirmed from the results of iterated tests. The power of the fabricated cell is greater than 1.1 W cm⁻² at 600 °C, which is a record high for PCFCs and is reproducible. In this paper, the origin of this high power is discussed and improvements that could be made to cell performance are further suggested.

Y：Ba（Ce，Zr）O3电解质厚1 µm的高性能质子陶瓷燃料电池

这项研究证明了使用薄膜电解质增强质子陶瓷燃料电池（PCFC）的有效性。在这项研究中测试的材料是掺钇的铈酸锆锆钡（BCZY），它是PCFC的代表性电解质材料。电解质膜的厚度小至1 µm，旨在将质子传输路径中的欧姆损失降至最低。试图在多层阳极上集成这种薄BCZY电解质，该阳极由两步支撑组成，其中镍基稳定的氧化锆金属陶瓷以块状镍-氧化锆为基体，而镍-BCZY镍薄层为基体顶部的阳极功能层。该载体与沉积的薄电解质的相容性可以从反复测试的结果中确认。人造电池的功率大于1.1 W cm ^-2在600°C的温度下，这是PCFC的最高记录，并且具有可重现性。在本文中，讨论了这种高功率的起源，并进一步提出了可以改善电池性能的建议。
