Abstract
This invention describes the recipe and preparation process of nano-scale electrolyte suspension and its application via a spin coating process for fabrication of airtight/fully dense electrolyte layers composed in solid oxide fuel cell-membrane electrode assembly with high performance characteristics. The recipe of nano-scale electrolyte suspension includes 10˜50 wt % nano-scale electrolyte powder, 0.01˜1 wt % poly acrylic acid (PAA as dispersant), 0.1˜5 wt % poly vinyl alcohol (PVA as binder), 0.005˜1 wt % octanol as defoamer, and deionized water as solvent. Solid oxide fuel cell fabricated via this recipe and process exhibits that the open-circuit voltage (OCV) is over 1 Volt, and maximum power density is 335 mW/cmat 800° C.
