A comparison of steam reforming concepts in solid oxide fuel cell systems

Various concepts have been proposed to use hydrocarbon fuels in solid oxide fuel cell (SOFC) systems. A combination of either allothermal or adiabatic pre-reforming and water recirculation (WR) or anode off-gas recirculation (AOGR) is commonly used to convert the fuel into a hydrogen rich mixture before it is electrochemically oxidised in the...

Dynamic modelling of a direct internal reforming solid oxide fuel cell stack based on single cell experiments

Direct internal reforming enables optimal heat integration and reduced complexity in solid oxide fuel cell (SOFC)systems, but thermal stresses induced by the increased temperature gradients may inflict damage to the stack. Therefore, the development of adequate control strategies requires models that can accurately predict the temperature...
