Abstract

Based on the models of the porous-electrode, a lattice Boltzmann model of a solid oxide fuel cell is presented, which allows the computation of the local distributions of the electrical potential, current density, and concentration of the chemical species. The physics of the cell and the simplifying assumptions are presented; a sketch of the numerical procedure is also given. The numerical results obtained with hydrogen as the fuel are compared with results from other simulation codes which were developed for a planar geometry. The numerical results show that the counter-flow design as being the most efficient. Furthermore, and with increasing the percent H2in the fuel stream, the voltage drops profile alters from precipitous to gentle. These results are excellent.
