natural gas, coal gas, etc.) became one of the main topics of SOFC research within the last
years. Fuel gases like methane can be steam-reformed or partially oxidized within the SOFC
stack. Usually a large amount of steam or air (steam to carbon ratio> 2) has to be applied to
avoid carbon deposition resulting in a degradation of the anode and a failure of the stack.
The influence of the steam to carbon ratio on the performance of planar state of the art SOFC …
