    摘要: A fuel cell has a MEMS fuel-cell structure including an anode, a cathode, and an electrolyte, formed on a substrate, a portion of the substrate being removed from beneath the MEMS structure to leave the MEMS structure suspended in membrane form. An opening may extend through the substrate to leave the MEMS fuel-cell structure in a cantilevered configuration, supported by only one edge. Additional openings may be formed to relieve mechanical stress near an edge or edges supporting the MEMS fuel-cell structure, and/or to limit heat-conducting paths. Specially adapted methods are disclosed for fabricating the MEMS-based fuel cell in any of its various configurations.

    摘要: An electrode suitable for use in a fuel cell includes a passive support having pores wherein the passive support has an asymmetric pore morphology with respect to at least one dimension of the passive support; and an electrode material positioned in the pores of the passive support. An exemplary electrode includes an electrode material of a metal and/or metal oxide. An exemplary porous electrode includes a deposited electrolyte layer that blocks at least some pores of the porous electrode. An exemplary method includes reducing an electrode material positioned in pores of a passive support to create secondary porosity and/or to limit agglomeration. Other exemplary devices and/or methods are also disclosed.
