On the influence of geometric microstructural properties of porous materials on the modelling of a tubular fuel cell

A numerical model of tubular solid oxide fuel cell (SOFC) with simplified one-dimensional current flux prediction is examined. The model takes into a ccount geometric properties of porous sinters used for anode and cathode. Three characteristic parameters, i. . porosity, tortuosity and mean pore radii have been considered. The obtained numerical results all ow one to estimate the influence of various geometr ic properties of porous materials on the fuel cell per formance by means of average and local variables.
