Thermal imaging of solid oxide fuel cell anode processes

Anode regeneration following carbon depositions in an industrial-sized anode supported solid oxide fuel cell operating on synthetic diesel reformate

“…By means of these data, it can be assumed that the "voltage decrease phenomena" illustrates the process of carbon deposition. The available literature presents the CO 2 -peaks during the carbon formation due to operation with methane -dry as well as humidified (see Refs [10,20]), while Pomfret et al [50] showed decreased temperature due to carbon depositions, but for the cells fueled with hydrocarbon.…”

Temperature distribution on anodic surface of membrane electrode assembly in proton exchange membrane fuel cell with interdigitated flow bed

“…Therefore, observing the exterior temperature gradient of a fuel cell is an effective approach. Pomfret et al [16] measured temperature distribution on the anode surface of an operating SOFC with an infrared imaging system similar to a Si chargecoupled device imaging machine, which has a spatial resolution of 0.1 mm and a temperature measurement accuracy of 0.1 C.…”

Highlighting of Critical Experimental Data for SOFC Modeling That is Missing From the Literature and Potential of N-IR Thermography for SOFC Study

“…[2][3][4][5][6], have measured temperature profiles, in detail, longitudinally along the outside of solid oxide fuel cell (SOFC) electrodes. However, measured temperature profiles, radially through the electrode/electrolyte/ counter-electrode interfaces, or in other words perpendicular to the electrolyte, have not been recorded and published in the scientific literature.…”

“…The rapid measurement response enables recording of dynamic phenomena, which is a novel feature. Furthermore, such measurements can reveal spatially resolved details regarding temperature changes due to reduction and oxidation reactions as well as carbon deposition and re-oxidation at the anode electrode material surface [3]. Recording measurements in the near infra red (N-IR) range affords cameras and optical components that are less expensive and, in many respects, yield better performance than conventional IR cameras [25].…”

“…The fact that bodies at temperatures above 500 C certainly emit electromagnetic radiation wavelengths in the 0.8 lm to 1.2 lm range, which can be detected by CCD devices [3,27,28] affords CCD N-IR measurements. For example a similar technique used by Dhokkar et al [29] has been used in order to study transistor technology temperature fields in the micro scale.…”
