Modeling of solid oxide fuel cells

Solid oxide fuel cell(SOFC)is a high temperature(800-1000℃)power source,which can directly convert the chemical energy of a fuel into electrical energy via electrochemical reactions.As the energy conversion process is straightforward,the electric efficiency of SOFC(>50%)is considerably higher than that of conventional heat engines(<40%).Compared with low temperature fuel cells,such as proton exchange membrane fuel

Solid oxide fuel cell （SOFC） is a high temperature （800--1000℃） power source, which can directly convert the chemical energy of a fuel into electrical energy via electrochemical reactions. As the energy conversion pro- cess is straightforward, the electric efficiency of SOFC （〉50 %） is considerably higher than that of conventional heat engines （〈40 %）. Compared with low temperature fuel cells, such as proton exchange membrane fuel cells （PEMFC） or alkaline fuel cells （AFC）, SOFCs are fuel flexible and can make use of various hydrocarbon fuels as internal reforming of hydrocarbon fuels can take place in the porous anode.
