In order to study the heat and mass transfer at the surface of porous media for fuel cell, we investigated experimentally and numerically fluid flow and heat and mass transfer in porous media and obtained the following results :1.The flow velocities in pore of porous media are measured by the laser Doppler velocimeter and the relation between the flow in the porous media and the flow along the surface is found.2.The lattice Boltzmann method is applied to simulations of flow and heat transfer in porous media with various porosity and the effect of the porosity on the flow and heat transfer is found.3.The mass transfer coefficients between the fluid and the porous media are measured by the electrochemical method.4.The lattice Boltzmann method is used for simulations of heat and mass transfer in porous media and the local heat and mass transfer coefficients are obtained.
