Bolt-microtubular cells (BMCs) are also constructed on BMASs to investigate the effects of the created surface patterns on the cell performance and microstructure. The bolt-microtubular cell, whose anode support is patterned by using a threaded rod with 0.8 mm thread pitch and 0.4 mm thread depth, exhibits similar to 92% higher maximum performance than that of the reference cell at 800 degrees C under 0.3 NL/min hydrogen flow and stagnant air. The almost doubled performance is mainly due to the increase in anode-electrolyte and cathode-electrolyte interfacial areas by the surface patterns created. The cell is also subjected to a 200-h life test at 800 degrees C and 0.7 V and demonstrates a stable performance.eninfo:eu-repo/semantics/closedAccessSolid oxide fuel cellMicrotubularSurface patterningBolt-microtubularTape castingArticle44127092710210.1016/j.jeurceramsoc.2024.05.0182-s2.0-85192923220Q1WOS:001249086300004N/A
