Solid oxide fuel cells (SOFCs) are being extensively researched for clean power generation from coal‐derived syngas. Some of the contaminants in syngas such as phosphine (PH 3 ) may interact with the SOFC anode material, and degrade its electrochemical performance and material properties. In this paper, a modified Sagnac interferometry method is utilized to monitor the anode surface transient temperature as a function of applied current densities under hydrogen and simulated coal syngas. Moreover, the poisoning effects of PH 3 contaminant on the SOFCs performance are investigated in dry and moist conditions. The experimental results indicate that the Ni‐cermet‐based SOFC anode is more susceptible to degradation due to PH 3 in the presence of steam than under dry conditions. These experiments are valuable for the validation and the development of SOFC electrochemical models, and understanding the anode‐contaminant interaction.
