Solid oxide fuel cells with atomic layer-deposited thin film electrolytes supported on anodic aluminum oxide (AAO) are electrochemically characterized with varying thickness of bottom electrode catalyst (BEC); BECs which are 0.5 and 4 times thicker than the size of AAO pores are tested. The thicker BEC ensures far more active mass transport on the BEC side and resultantly the thicker BEC cell generates ≈11 times higher peak power density than the thinner BEC cell at 500 °C.
具有阳极氧化铝（AAO）支撑的原子层沉积薄膜电解质的固体氧化物燃料电池，通过改变底部电极催化剂（BEC）的厚度进行电化学表征；测试了比AAO孔径厚0.5倍和4倍的BEC。较厚的BEC确保了BEC侧有更多的活性物质传输，因此在500℃时，较厚BEC的电池产生的峰值功率密度比较薄BEC的电池高约11倍。
