An integrated catalytic steam reforming fuel cell electrode

摘要

The invention relates to the production of a steam reforming- fuel cell system in which a catalytic steam reforming layer is directly integrated into a fuel cell device by being co-sintered with the fuel cell anode. The system is thus able to cogenerate H 2 and electricity from glycerol by an electro-catalytic process. The reforming layer may be composed of a combination of two metals, e.g. Mo-Ti, Cu-Ti, Mo-Cu, Mo-W mixed within gadolinia doped ceria with the advantage of being able to tolerate large amount of sulphur often contained in sources of glycerol produced from bio-mass. The invention relates also to a system having a specific geometry, e. g. a tubular geometry. The invention also relates to a method of operating the system where the control of the injection, e.g. by employing a pulsed injection, with the advantage of regenerating the catalytic reforming layer without the need of shutting down the system.
