摘要:

质子陶瓷膜燃料电池(PCFC)因可降低固体氧化物燃料电池的工作温度而备受关注,而管式质子陶瓷膜燃料电池相对于平板状电池具备体积功率密度高、机械强度高等优势。为了简化大尺寸管式PCFC的制备过程,使用中空且顶端带有微小孔隙的玻璃管作为制备阳极支撑体的模具,通过相转化的方法使用原料粉一步制备NiO-BaCe0.7Zr0.1Y0.1Yb0.1O3(BCZYYb)的阳极支撑。同时探索不同的烧结方式以减少陶瓷基板对管式PCFC电解质陶瓷膜的影响。高温共烧结之后通过扫描电子显微镜(SEM)观察到阳极支撑体内存在大量的连通孔隙,同时浸涂覆法制备出30 μm厚的致密BZCYYb电解质层。管式PCFC以湿润氢气为燃料、环境空气为氧化剂在600 ℃的最大功率密度是80 mW/cm2,欧姆阻抗为14 Ω·cm2,极化阻抗为16 Ω·cm2。通过相转化和固相反应烧结的手段,从原料粉体一步制备成管式PCFC电池,该管电池和制备方法可应用于PCFC管式电池的大规模应用。

Abstract:

Proton ceramic fuel cells (PCFCs) attract great attention for being of lower operating temperatures than solid oxide fuel cells.Furthermore,tubular PCFCs are of higher power density and higher mechanical strength compared with planar PCFCs.To simplify the preparation of large-size tubular PCFCs,hollow glass tubes with tiny pores at their tops are taken as the preparation mold for the anode supporting layers,and the NiO-BaCe0.7Zr0.1Y0.1Yb0.1O3(BCZYYb) anode support is made from raw material powder by one-step preparation based on phase inversion mechanism.To reduce the impact of the ceramic substrates on the tubular PCFC electrolyte ceramic films,various sintering methods are explored.The scanning electron microscope(SEM) image of an anode support after high-temperature co-sintering presents that there are a large number of connected pores in the anode support.Dip-coating method provide the anode support with a 30 μm dense BZCYYb electrolyte layer.At 600 ℃,the power density of the tubular PCFC with humid hydrogen as fuel and ambient air as oxidant can peak at 80 mW/cm2,and the ohmic resistance and polarization resistance can reach 14 Ω·cm2 and 16 Ω·cm2,respectively.The one-step preparation method integrated phase inversion mechanism and solid reaction sintering can make tubular PCFCs from raw materials powder,which can be applied to large-scale tubular PCFC production.
