Patent number: 10344387Abstract: The solar fuels generator includes an ionically conductive separator between a gaseous first phase and a second phase. A photoanode uses one or more components of the first phase to generate cations during operation of the solar fuels generator. A cation conduit is positioned provides a pathway along which the cations travel from the photoanode to the separator. The separator conducts the cations. A second solid cation conduit conducts the cations from the separator to a photocathode.Type: GrantFiled: October 24, 2016Date of Patent: July 9, 2019Assignee: California Institute of TechnologyInventors: Nathan S. Lewis, Joshua M. Spurgeon

Publication number: 20130092549Abstract: A light-driven electrolytic cell that uses water vapor as the feedstock and that has no wires or connections whatsoever to an external electrical power source of any kind. In one embodiment, the electrolytic cell uses a proton exchange membrane (PEM) with an IrRuOx water oxidation catalyst and a Pt black water reduction catalyst to consume water vapor and generate molecular oxygen and a chemical fuel, molecular hydrogen. The operation of the electrolytic cell using water vapor supplied by a humidified carrier gas has been demonstrated under varying conditions of the gas flow rate, the relative humidity, and the presence or absence of oxygen. The performance of the system with water vapor was also compared to the performance when the device was immersed in liquid water.Type: ApplicationFiled: April 2, 2012Publication date: April 18, 2013Applicant: CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Joshua M.

Patent number: 8110898Abstract: A structure consisting of well-ordered semiconductor structures embedded in a binder material which maintains the ordering and orientation of the semiconductor structures. Methods for forming such a structure include forming the semiconductor structures on a substrate, casting a binder material onto the substrate to embed the semiconductor structures in the binder material, and separating the binder material from the substrate at the substrate. These methods provide for the retention of the orientation and order of highly ordered semiconductor structures in the separated binder material.Type: GrantFiled: July 18, 2008Date of Patent: February 7, 2012Assignee: California Institute of TechnologyInventors: Nathan S.
