===Balance of plant===
Most of the downtime of a SOFC is caused by the mechanical [[balance of plant]] (from components like the [[air preheater]], [[prereformer]], [[afterburner]], [[water heat exchanger]], and [[anode tail gas oxidizer]]) and the electrical balance of plant (including the [[power electronics]], [[hydrogen sulfide sensor]] and fans). By using internal reforming (converting methane into hydrogen internally), lower cooling requirements are needed, helping decrease the complexity and costs of the [[balance of plant]].<ref name="e-collection.ethbib.ethz.ch"/>
