Abstract: A membrane electrode assembly for a fuel cell comprises a proton exchange membrane having an anode side and a cathode side. An anode catalyst layer is on the anode side of the proton exchange membrane and a cathode catalyst layer is on the cathode side of the proton exchange membrane. Each of the anode catalyst layer and the cathode catalyst layer comprises a metal alloy. A gas diffusion layer is on each of the anode catalyst layer and the cathode catalyst layer opposite the proton exchange membrane. A sacrificial intercalating agent is between the proton exchange membrane and one of the anode catalyst layer and the cathode catalyst layer, the sacrificial intercalating agent having sulfonate sites that attract metal cations resulting from dissolution of the metal alloy prior to the metal cations reaching the proton exchange membrane.

Abstract: An electrode comprises a current collector, a conductive buffer layer formed on the current collector that has at least one geometrically configured region and an active material layer formed on the conductive buffer layer. The geometrically configured conductive buffer region can expand and contract between the non-lithiated and lithiated states.

Abstract: A battery has a three dimensional electrode including a current collector, electron directing members, each electron directing member having a perimeter edge attached to a surface of the current collector with a polymer binder, the electron directing members extending from the surface of the current collector and configured to direct electron flow along a layered direction of the electrode, an active material layer on the current collector and a separator. The electron directing members extend into the active material layer and having a free end in spaced relation to the separator.

Abstract: A membrane electrode assembly includes a membrane, a gas diffusion layer and a catalyst layer between the membrane and the gas diffusion layer. The catalyst layer comprises catalyst comprising active catalyst particles supported on support particles, a proton conducting ionomer and a phospholipid containing soluble oxygen. One method of preparation includes preparing a catalyst solution comprising a solvent and catalyst, adding proton conducting ionomer to the catalyst solution to form a catalyst ink, saturating a solution of solvent and a phospholipid with oxygen and mixing the saturated phospholipid with the catalyst ink.

Abstract: An anode for a lithium-ion battery includes a current collector, a separator and an active material comprising alloying particles and a carbon material. A conductive net of carbon material surrounds the active material on at least the side walls and a separator-facing surface, the conductive net having net openings sized to retain the alloying particles and the carbon material within the conductive net while allowing lithium ions and electrons to pass through. The conductive net also maintains electrical contact between the carbon material and the alloying particles during lithiation and delithiation of the alloying particles.
