Abstract
A standard fuel cell requires hydrogen for operation; however, to achieve near-term applications fuel cells will need to use the existing infrastructure and already available fuels such as such as methane. Solid oxide fuel cells (SOFCs) are promising candidates for distributed stationary power generation. SOFCs can also use hydrocarbon-based fuel directly to generate electricity, but this solution does not exist in practice. Feeding methane straight into the anode, so-called direct reforming (DR) resulted in either carbon deposition at high temperatures or poor performance at low operating temperatures. To apply DR in practice, a better understanding of multi-physics phenomena inside SOFCs anode is needed. Combined numerical and experimental analysis can put an additional spotlight on the complex direct reforming phenomenon. In this study, a microstructure-orientated model for the description of micro-scale transport phenomena, chemical and electrochemical reactions in an anode-supported solid oxide fuel cell was developed. The proposed mathematical and numerical model were falsificated by the comparison of calculated current-voltage characteristics with the experimental ones. The obtained results indicated that the proposed model is not false and can be used for further analysis. © ECOS 2019 - Proceedings of the 32nd International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems.
