Abstract:

A mathematic model is used to describe the mass transfer of mulfticomponents [O2, H2O(g), N2] in the gas diffusion layer of air electrodes of phosphoric acid fuel cells (PAFC). A program of solving this mathematic model is designed with FORTRAN77. The main factors effecting the efficiency of mass transfer in gas diffusion layer are predicted by means of the numberical analysis of the proposed model. The range of these fartors allowed to change is also determined.

Key words: Fuel cells, Air electrodes, Mass transfer, Mathematic model
