    摘要： A method for manufacturing a fuel cell stack body includes a step of forming a plurality of line-shaped separator cross-sectional patterns. In the patterns, a first direction along the build surface is the stacking direction, and a second direction orthogonal to the first direction is the planar direction of the separators. The patterns extend in the second direction and meander so as to have convexities and concavities in the first direction. The manufacturing method further includes a step of forming the electrolyte membrane cross-sectional pattern and a step of forming the electrode cross-sectional patterns. These steps are repeated to perform stacking in a direction perpendicular to the build surface.

    摘要： Embodiments relate to a fuel cell including, an ion conducting component, two or more electrode coatings and one or more interconnects. The interconnects include a non-conductive interface region having a first surface and a second surface in which the first surface is in contact with the ion conducting component, an electron conducting component having two surfaces and a length that is parallel to the two surfaces wherein one of the surfaces is disposed adjacent to the second surface of the interface region. The electron conducting component provides an electrically conductive pathway between one of the electrode coatings and an external circuit, said pathway extending along the length of the electron conducting component.

    摘要： A membrane electrode assembly and fuel cell having such assembly. The membrane electrode assembly has a polymer electrolyte membrane, two catalytic electrodes in contact with the polymer electrolyte membrane on both sides, namely an anode and a cathode, and two gas diffusion layers directly or indirectly adjoining the electrodes, namely an anode-side gas diffusion layer and a cathode-side gas diffusion layer. At least one of the gas diffusion layers may optionally feature a microporous layer facing the polymer electrolyte membrane. The sequence of layers is anode-side gas diffusion layer, anode-side microporous layer, anode, polymer electrolyte membrane, cathode, cathode-side microporous layer, cathode-side gas diffusion layer. A relative hydrophobicity of at least two of these components and/or a hydrophobicity gradient within at least one of these components, and a relative pore structure having pore size and/or porosity of at least two of these components and/or a gradient within the pore structure of at least one of these components, is designed in such a way that it promotes the transport of water via the polymer electrolyte membrane, preferably from the cathode side to the anode side.
