With regard to a kind of proton exchange membrane fuel cell humidifier using porous media plate,an experimental measurement system was set up to study the characteristics of the heat and moisture transfer through the porous media plate. Using this system,the temperature,the relative humidity and the flow rate of humidifying(the exhaust gas of fuel cell)and humidified(the cathode gas of fuel cell)gas were measured,and the influences of those factors on the characteristics of heat and moisture transfer throug...
