Patent ID: 7829211

Claim:
A DMFC comprising: a. a cathode gas diffusion layer; b. an anode gas diffusion layer; c. a methanol storage medium, characterized by a first porous layer and configured to receive, temporarily store and permit the egress of methanol; and d. a mixing medium, characterized by a second porous layer and disposed adjacent the anode gas diffusion layer and the methanol storage medium or a methanol distribution medium, the mixing medium being configured to receive methanol and water, permit the methanol and water to mix and allow the methanol and water to transfer to the anode gas diffusion layer; and the methanol distribution medium, characterized by a third porous layer disposed between the methanol storage medium and the mixing medium wherein the methanol distribution medium is configured to receive methanol and distribute the methanol from the methanol storage medium to the mixing medium with a substantially uniform flow profile.
