A two - dimensional model of water transport is developed to investigate the distribution of water in the membrane

the distribution of the rate of water transport

the distribution of current density in the proton- exchange membrane fuel cell(PEMFC) . The effects of cell temperature

pressure difference between cathode and anode

humidification and thickness of membrane on water transport and distribution of water in the membrane are studied systematically. The conclusions from the model are as follows: ① If the anode is humidified

the water content on the anode side membrane in the reactant gas entrance can be increased; ② The thinner the membrane used

the higher the water content in the membrane;③ The higher the anode is humidified

the more water will migrate from anode to cathode.
