Advanced operando thermal imaging of planar SOFCs represents the frontier of electro-thermal characterization in the past few years. By integrating a quartz optical window into the test fixture, researchers can visualize real-time temperature gradients, hotspots, and redox dynamics that are otherwise invisible to standard thermocouples.
Designing a planar fixture with optical access requires balancing hermeticity (gas-tightness) with transparency. (1) Quartz Window Selection: Synthetic quartz or sapphire is used for its high transmissivity (>90%) in the 1.0 – 5.0 um range, which aligns with the mid-infrared (MWIR) cameras typically used for high-temperature thermography. (2) Window Placement: The window is usually integrated into the cathode manifold, allowing a direct line-of-sight to the electrode surface. This requires specialized high-temperature seals (e.g., gold gaskets or custom glass-ceramic) to prevent air from leaking into the fuel stream or cooling the cell surface prematurely. (3) Reflectivity & Emissivity: Since ceramics like LSM or LSC have high emissivity (~0.95-0.98), they are ideal for IR imaging. However, metallic components (interconnects) have low emissivity and can act as mirrors, reflecting the furnace elements. Proper emissivity correction is the most critical step in data post-processing.
