A cellular material includes a continuous solid phase including an ordered ceramic material, the solid phase having a solid core including the ordered ceramic material. A composition for forming a cellular material includes: a first UV curable pre-ceramic monomer; a second UV curable pre-ceramic monomer; and a photoinitiator. A method of forming at least one ceramic waveguide includes: securing a volume of a composition including a UV curable pre-ceramic monomer; exposing the composition to a light source to form at least one polymer waveguide including a pre-ceramic material; and converting the pre-ceramic material of the polymer waveguide to a ceramic material to form a ceramic waveguide.

A ceramic micro-truss structure. In one embodiment green state polymer micro-truss structure is formed by exposing a photomonomer resin through a mask to collimated light from three or more directions. The green state polymer micro-truss structure is shaped and post-cured to form a cured polymer micro-truss structure. The cured polymer micro-truss structure is pyrolyzed to form a ceramic micro-truss structure, which may subsequently be coated with metal.

Pre-ceramic monomer formulations for creating self-propagating polymer waveguides, and a system and method of using the same, is disclosed. The formulation includes a plurality of unsaturated molecules, wherein the unsaturated molecules contain a significant amount of non-carbon atoms, a molecule having structure of R'&#x2014;X1-H (e.g., X1=O, S, N), and a photoinitiator. R&#x2032; can also have non-carbon atoms. The system includes a light source, a reservoir having a monomer formulation and a patterning apparatus configured to guide a light beam from the light source into the pre-ceramic monomer formulation to form at least one self-propagating polymer waveguide and can be directly converted to interconnected three-dimensional ceramics.

The present invention provides methods for fabricating a fuel cell membrane structure that can dramatically reduce fuel crossover, thereby improving fuel cell efficiency and power output. Preferred composite membrane structures include an inorganic layer situated between the anode layer and the proton-exchange membrane. The inorganic layer can conduct protons in unhydrated form, rather than as hydronium ions, which reduces fuel crossover. Some methods of this invention include certain coating steps to effectively deposit an inorganic layer on an organic proton-exchange membrane.
