The present study is focusing on the elaboration of the quantitative relationships between the primary microstructural parameters (i.e. the phase volume fractions Phi, the particle and pore sizes and the corresponding size distributions PSD) with the more complex topological features (triple phase boundary length TPBL, and specific surface area SSA) in porous Ni-cermet anodes. These relationships are crucial for the microstructure optimization and for the improvement of the corresponding electrode performance.
