Oxidation of H2, CO and methane in SOFCs with Ni/YSZ-cermet anodes

A Weber, B Sauer, AC Müller, D Herbstritt… - Solid State Ionics, 2002 - Elsevier
The operation of solid oxide fuel cells with the use of different types of carbon-based fuels (ie
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 …
