摘要: 塑性挤压成型阳极支撑管,采用真空浸涂法在阳极表面制备了均一、致密的氧化钇稳定的氧化锆电解质层,然后在电解质表面刷涂上阴极层,成功制备了阳极支撑型管状固体氧化物燃料电池. 分别以氢气和氨气为燃料,考察了该管状固体氧化物燃料电池的电池性能. 在800 ℃操作时,以氢气和氨气为燃料的电池最大输出功率密度分别为202和200 mW/cm2. 表明氨气可以作为固体氧化物燃料电池的替代燃料.

Abstract: A Ni-anode-supported tubular solid oxide fuel cell (SOFC) with a dense yttria-stabilized zirconia (YSZ) thin film was fabricated. The YSZ film was prepared using the vacuum-assisted dip-coating method. The performance of the single SOFC-based system running on ammonia was compared with that running on hydrogen. At 800 ℃, the peak power densities were 202 and 200 mW/cm2 with hydrogen and ammonia as the fuel, respectively. A GC analysis of the effluent from the anode showed considerable amounts of nitrogen and hydrogen, but no trace of NOx, when using ammonia as the fuel. The ammonia performance is comparable to hydrogen, suggesting that ammonia can be an attractive alternative fuel.

Key words: ammonia, vacuum-assisted dip-coating, anode-supported tube, solid oxide fuel cell
