Solid oxide fuel cells are a class of fuel cells characterized by the use of a solid oxide material as the electrolyte. SOFCs use a solid oxide electrolyte to conduct negative oxygen ions from the cathode to the anode. The electrochemical oxidation of the hydrogen, carbon monoxide or other organic intermediates by oxygen ions thus occurs on the anode side. More recently, proton-conducting SOFCs (PC-SOFC) are being developed which transport protons instead of oxygen io… WebJul 11, 2024 · For the SOFC-based DC microgrid development, safe operating, including thermal management and gas starvation, is an important control task, especially the high operating temperatures may lead to the thermal gradient and local hot spots (Zhang et al., 2010).
