摘要： A technique for fabricating an MEA for a fuel cell that is prepared as a CCDM. The MEA includes a diffusion media layer having a microporous layer. A catalyst layer is deposited on the microporous layer so that it covers its entire surface. An ionomer layer is sprayed on the catalyst layer. A perfluorinated membrane is sandwiched between one CCDM at the anode side of the MEA and another CCDM at the cathode side of the MEA where the ionomer spray layers face the membrane.

摘要： A fuel cell including an anode-side catalyst coated diffusion medium and a cathode-side catalyst coated diffusion medium that sandwich an ionically conductive membrane. A sealing material is disposed between the ionically conductive membrane and the anode-side and cathode-side catalyst coated diffusion medium, wherein the sealing material is formed of a material that has a permeability that is less than a permeability of the ionically conductive member. The sealing material may also be formed of a material that is softer than the ionically conductive membrane such that the sealing material may deform and enable an membrane electrode assembly of the fuel cell to be subjected to uniform pressures throughout the assembly.

摘要： A fuel cell that includes a blocking agent for preventing hydrogen and air from contacting bare membrane. This in turn prevents the reaction of air and hydrogen gases at outside edges of the catalyst layers. The blocking agent is deposited within diffusion media layers on one or both of the anode and cathode sides of the fuel cell. The blocking agent extends into the diffusion media layers far enough so that it is within outside edges of the catalyst layers. In one embodiment, the blocking agent is a thermoplastic polymer, such as PVDF, that flows into the diffusion media layers in a melted format, where it hardens.

摘要： A diffusion media for use in a PEM fuel cell which includes a relieved edge region relative to the interior region of the diffusion media. The outer perimeter or portion of the diffusion media that will interface with a sealing gasket is pre-compressed. The pre-compressed diffusion media lowers the compression stress on the MEA at the gasket interfaces, enabling a more uniform compression on the entirety of the MEA surfaces during the build, compression, and later operation of a fuel cell stack.
