PENETRATION RATE OF ELECTROLYTE INTO PORE OF MCFC CELL COMPONENTS

The present study is focused on clarifying the relationship between th e weight gain due to the permeation of the electrolyte and the permeab ility of the electrolyte into the pores of MCFC components such as ano de, cathode and electrolyte matrix. The relationship between the weigh t gain and the electrolyte permeability has been derived from the equa tion for the capillary rise phenomenon(16)). It was found that the ele ctrolyte permeation rate was proportional to the square root of pore d iameters. Thus determined penetration rate showed that the permeation rate for the both anode and cathode was about 50 times faster than tha t for the electrolyte matrix.
