SOFC mathematic model for systems simulations. Part one: from a micro-detailed to macro-black-box model

In applying the local equations as “global”, however, some problems can arise. In the present work, a review of the most significant SOFC models is conducted and then the possibility of their use in a macro-model is evaluated. Different results can be generated according to the assumptions made when adapting micro-model equations to a macro-model. A quantitative analysis of these differences is finally performed and the reliability of the model is estimated.
