Abstract
It is expected that fuel cells will play a significant role in a future sustainable energy system. They are energy efficient and fuel can be produced nearly locally. There are no net emissions of greenhouse gases when a renewable fuel such as ethanol, methanol, biogas and hydrogen is used. Fuel cells reached during the latest years various progresses, but the technology is still in the early phases of development, however the potential is enormous.

The reforming reaction of hydrocarbons (e.g., methane) is a key one for an effective solid oxide fuel cell (SOFC) operation. This reaction could either be described by global kinetics or by elementary surface reaction kinetics. When a global approach is applied, the reaction rates... (More)
It is expected that fuel cells will play a significant role in a future sustainable energy system. They are energy efficient and fuel can be produced nearly locally. There are no net emissions of greenhouse gases when a renewable fuel such as ethanol, methanol, biogas and hydrogen is used. Fuel cells reached during the latest years various progresses, but the technology is still in the early phases of development, however the potential is enormous.

The reforming reaction of hydrocarbons (e.g., methane) is a key one for an effective solid oxide fuel cell (SOFC) operation. This reaction could either be described by global kinetics or by elementary surface reaction kinetics. When a global approach is applied, the reaction rates depend on temperature, partial pressures, activation energy and the pre-exponential factor. Note that the last two mentioned parameters are normally calculated from experimental data. Different detailed reaction mechanisms (considering elementary surface kinetics) are developed, but there is a disagreement considering the involved reaction pathways, rate-limiting steps and intermediate species. It is found that detailed kinetics of the reforming reaction is important for design and development of new effective catalytic materials. A thermodynamical analysis tells that nickel and ruthenium are suitable catalytic materials for the methane steam reforming reactions. (Less)
