ABSTRACT:
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.
