Patent number: 10408997Abstract: 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.Type: GrantFiled: December 9, 2015Date of Patent: September 10, 2019Assignee: HRL Laboratories, LLCInventors: Zak C.

Patent number: 9160013Abstract: 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.Type: GrantFiled: April 13, 2014Date of Patent: October 13, 2015Assignee: HRL Laboratories, LLCInventors: Adam F.
