    摘要: Methods of manufacturing electrochemical cells having a current collector which, at least in part, underlies a catalyst layer are discussed. A method comprises patterning a current collector to have at least one electrolyte opening, disposing an electrolyte into or through the at least one opening, and disposing a catalyst, at least in part, over the disposed electrolyte. Optionally, the method comprises pattering a substrate and attaching a patterned current collector to each side thereof. Patterning of the current collector can include patterning a continuous sheet, which comprises at least a first and a second separable current collector. In one such example, a continuous carbon-fiber sheet impregnated or laminated with a non-porous material is patterned. In another such example, a continuous plastic material sheet impregnated with one or more electrical conductive particles is patterned. Among other things, the pattern of the current collector can include an extruded slot or adjacently-disposable strips.

    摘要: Embodiments of the invention relate to electrochemical cells and membranes including alternating electrically conductive and dielectric regions. One embodiment describes an ion-conducting composite layer for an electrochemical cell, including two or more electrically conductive components, each electrically conductive component having one or more electrically conductive passageways and one or more dielectric components, each dielectric component having one or more ion-conducting passageways. The electrically conductive components and the dielectric components are adjacently arranged to provide a fluidically impermeable composite layer.

    摘要: Fuel cell systems and methods having reduced volumetric requirements are described. The systems include, among other things, an enclosed region formed by the bonding of a fuel cell layer with a fluid manifold. The enclosed region transforms into a fluid plenum when, for example, a fluid exiting a manifold outlet pressurizes the enclosed region causing one or more portions of the fuel cell layer and/or the fluid manifold to deform away from each other.

    摘要: A fuel cell system including, among other things, one or more of a fuel cell, a fuel reservoir, a current collecting circuit, a plenum, or a system cover. The fuel reservoir is configured to store fuel, and may include a regulator for controlling an output fuel pressure and a refueling port. A surface of the fuel reservoir may be positioned adjacent a first fuel cell portion. The current collecting circuit is configured to receive and distribute fuel cell power and may be positioned adjacent a second fuel cell portion. The plenum may be formed when the fuel reservoir and the first fuel cell portion are coupled or by one or more flexible fuel cell walls. The system cover allows air into the system and when combined when a fuel pressure in the plenum, may urge contact between the fuel cell and the current collecting circuit.
