NOVELTY - A fuel cell (10) comprises membrane electrode assembly (12) disposed between first diffusion media (14) having first set of material and second diffusion media (16) having second set of material. Membrane electrode assembly and second diffusion media providing cell assembly have water transport mechanism selectively controlling water transportation across thickness of first diffusion media, and across thickness of second diffusion media. First set of material has at least one material different from at least one material of second set of material.    USE - Method for manufacturing a fuel cell.    ADVANTAGE - The anode of fuel cell is generally operated at relatively lower stoichiometry, thus most of pure hydrogen gas is consumed near anode gas outlet.    DETAILED DESCRIPTION - Fuel cell (10) comprises membrane electrode assembly (12) disposed between first diffusion media (14) having first set of material and second diffusion media (16) having second set of material. Membrane electrode assembly and second diffusion media providing cell assembly have water transport mechanism selectively controlling water transportation across thickness of first diffusion media, and across thickness of second diffusion media. First set of material has at least one material different from at least one material of second set of material. Water transport mechanism is defined by difference between at least one material of first and second set of material to manage hydration of first and second diffusion media. An INDEPENDENT CLAIM is included for manufacturing fuel cell stack which comprises selecting first diffusion media having first set of material; selecting second diffusion media having second set of material characteristics; and selectively controlling water transportation with water transport mechanism.
